Array to elements

Hello to all,
I am creating a program and, at this point, I need to extract an indefinite number of items from an array. If I knew the exact number of elements to extract there is no problem but how do I do not know this number?
thanks

You certainly won't be able to use Arrray to Cluster without providing a cluster size to the primitive; this needs to be known at design-time. Answer pincpanter and someone can suggest an alternative.
<mta> You posted as I was writing mine. What do you mean by "bind (as appropriate) to a case structure"? It sounds like you want to have the array elements become individual cases in the Case structure. Is that correct? That's another design-time decision.

How to insert 2-D array of elements in excel sheet

I have a 2-D array of elements. I want to insert this array into an excel sheet and display the data in a graph. I used the example "excel insert table" but the problem with that VI is, it is inserting the elements cell by cell which is taking long time. I am wondering whether there is way to insert a complete column or row into excel sheet at a time.
Thank you,
Mudda.

Hi,
Try this vi which inserts the table in one operation. You can modify it to suit your purposes.
Hope this helps.
Edit: Should note that it works for both string and numeric array inputs.Message Edited by DavidT on 06-29-2005 10:09 AM

Array of cluster to array of element - or - Cluster of arrays?

Hi all,
I have a large cluster (lets call it C_data) containing measured data e.g. 10 Temperatures, Pressure, (Temp_1, ...).....
All these data are measured once per second. I now collect all data
measured over a certain time in an array of the aforementioned cluster,
that is
an array of C_data. In order to display time series of data in graphs I
need to extract arrays of elements from this array of C_data.
In a text based programming language this could look like the following:
Struct C_data {Temp_1, Temp_2, P_1.....}
ar_C_data is an array of C_data
now I want to do something like:
array_of_Temp_1 = ar_C_data[*].Temp_1
In some programming languages this works but I cannot unbundle_by_name the array of Temp_1 from ar_data in Labview.
Since my cluster is large and may change in structure (for this reason I use a typedef) a generic solution would be the best.
I know that I could: loop over all elements of ar_C_data, unbundle by
name, index elements into arrays, and use these but this seems very
inefficient if it is done every second on a large cluster (30 elements) with several thousand array elements....

You can minimize the overhead of scanning through all elements and extracting if you pre-define the array and use "replace array subset". This avoide having to re-size the array which is costly.
Or you can keep an array separately in memory. When one cluster element is added, the corresponding element is added to the array too. Causes some memory overhead, but you're going to have that anyway if you generate them "on the fly".
I don't see a way to do this other than either search through the array and pick the elements you need -or-
keep a copy of the data in a form you can use.
It's a common question of how to structure data to best suit two sometimes conflicting needs - efficiency and useability.
What might be of interest is to change the "Array" - "Cluster" order and have a single cluster C-Data with arrays of each element required. Might be a bit more difficult to use, it depends on your application.
This way you have all arrays ready at all times, but generating a single cluster requires bundling the individual units on the fly.

Creating array of references to another array's elements

I have been coached by NI support to read an array of picture files into an array of picture indicators and then in order to save memory, establish an array of references to the array of picture indicators' elements so that I can use them in a subsequent loop. Does anyone know a quick way to create this array of references from an array of picture indicators?
Solved!
Go to Solution.

My understanding is there is only one reference to an array element. There is no such thing as references to different array elements.
Why wouldn't you use a reference to the array, use the value property node, then use index array to get out the picture you are interested in?

Complex types with single array type element, marshaling exception

For our JAXRPC web service, we have a complex type, as follows:
<xs:complexType name = "SomeFault">
<xs:sequence>
<xs:element name = "errorMessages" type="some:ErrorMessageWSType" minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:simpleType name = "ErrorMessageWSType">
<xs:restriction base = "xs:NMTOKEN">
<xs:enumeration value = "INVALID_1"/>
<xs:enumeration value = "INVALID_2"/>
<xs:enumeration value = "INVALID_3"/>
</xs:restriction>
</xs:simpleType>
We are running into Marshaling exceptions on the server side when the response/fault complex type has a single array type field.
weblogic.wsee.codec.CodecException: Failed to encode
com.bea.xml.XmlException: failed to find a suitable binding type for use in marshalling object "[Lnamespace.type.ErrorMessageWSType;@693767e9". using schema type: t=SomeFault@http://namespace/SOME/v1 java type:namespace.type.ErrorMessageWSType[]
If I change SomeFault, by adding another element, the error goes away.
<xs:complexType name = "SomeFault">
<xs:sequence>
<xs:element name = "errorMessages" type="some:ErrorMessageWSType" maxOccurs="unbounded" />
<xs:element name = "dummyString" type="xsd:string" minOccurs="0" />

Am I doing something wrong during the wsdlc code generation or is this a known issue?

Any luck with this? I am running into the same error. Apparently, this is not an issue with Java binding, but when invoking remote EJBs, we run into this. I am running 10.1.3.1 and the error is:

Problem when getting array's elements in JSF

Using Struts/EJB/JSF.
Here is the code:
Action servlets code:
request.setAttribute("colSellers", (List<SellerDTO>) List );JSF part:
<c:out value="${colSellers[projectForm.client].id}"/>Error message:
*[ServletException in:/html/forms/project/read.jsp] The "[]" operator was supplied with an index value of type "java.lang.String" to be applied to a List or array, but that value cannot be converted to an integer.'*
But it works when i use real integer values....like
<c:out value="${colSellers['2'].id}"/>

Sorry, but this doesn't look like JSF, it looks like a combination of servlets, JSP EL and JSF. It will all work alot better if you choose your poison.
Put the array in a managed bean and use a JSF component like h:datagrid or t:datalist to display the elements. If that seems too restrictive, do what I did and switch to Spring MVC.

"Unique Key" in an array of elements

Hi all.
I'm attaching here a piece of an XSD I'm writing:
          <xs:element name="main_element" maxOccurs="unbounded">
       <xs:complexType>
          <xs:sequence>
               <xs:element name="key_element" type="xs:string"/>
                  <xs:element name="element_2" type="xs:integer"/>
             </xs:sequence>
          </xs:complexType>
          </xs:element>What I'd like is defining "key_element" as a unique key of the array "main_element", that is forcing the resulting array not to contain duplicate values for "key_element".
Is there any way to accomplish that?
Thanks in advance for any help!

Define key_element as a key (or unique)! Check the schema specification at http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions. If you're up to a challenge translate the specification from W3-ese to a meaningfult language, or take a short cut and read the example in section 3.11.2.
Support for keys in validation is sometimes spotty, but it's pretty easy to code up your own checks if needed.

Type casting an array as element

Hello all,
I'm relatively new to labVIEW and I would like your help with something.
Let us say I have an array of two I16 elements. I would like to type cast it into one single U32 element. In C, I could simple read it as a U32 or use pointers to get away with it, but I don't seem to be able to find a way to do it here.
Cheers,
S

You can, in fact, use the Type Cast function to do this. Alternately, index out the two array elements, then use Join Numbers to merge them.

Array(n elements) to string conversion

i got some questions about data conversion:
i have an array with n elements, witch i need to extract and convert to string in order to send data over udp vi. the problem is
that the vi is getting pretty big and i'm starting to wonder about memory&cpu usage. So can anyone check
this vi out and see if there is place for improvements.

array-string(6ch).vi ‏85 KB

I've done some more changes and hidden most of the code in a sub-vi. I've also shown how to make the code scalable, in case you suddenly need to accomodate 7 or 10 inputs.
In the new VI's, I've shown 2 different approaches to your code, but both are functionally equivalent.
As far as performance, you can always gain a little boost by going to File --> VI Properties --> "Execution" and deselect "Allow Debuging".
There might be other ways to optimize your code, but the thing you need to ask yourself is if this is really necessary.
If you go to File --> VI Properties --> Memory
you will see some "stats" for your current VI.
The one you posted originally, has a memory footprint of ~117.5k... as for cpu-usage, unless you are working with a significantly bigger project, you do not need to worry about performance at all, unless you are on a very very old computer.
That said, optimizing code is always important, and it is a very good way to learn, but sometimes one must be able to see when "enough is enough" and something is "good enough".
For comparision, the new VI I made for you, which includes 2 examples/different ways of doing it, takes only ~56.7k... though I'm not sure if you need to add the sub_vi to this or if it is already added.. the sub-vi is ~23.7k total..
Hope this helps you, and if someone else can take a look to see if there is any other obvious ways to optimize the code, then both me and the thread-owner will learn something more here.

Code hinting with array of elements

I am having an issue where I can get code hinting on the entire array, but not if a I specify an individual element.
Example
var dataFields = new Array();
var allElems = document.getElementsByTagName("*");
for (var i = 0; i < allElems.length ; i++) {
if (allElems[i].className == "classNameofElementIWant") dataFields.push(allElems[i]);
Above is what I use to get an array populated with a specific element I want to work with.
I can then get code hinting on dataFields.
but no code hinting on dataFields[1].
Obviously this is because the array doesn't have any elements in it until run time after it runs the above code.
My question:
Is there a way to tell code hinting to display using an array without the [] subscript specified when it can see that an array has no elements?
Thank you

Independent PtByPt calcs on array's elements

Hello,
I have a double array as an input, and at every iteration of the main VI, I would like to calculate mean and standard deviation separately on all the elements using PtByPt VI.
Fortunately in my case I know that, the array size is maximum 11. My solution works, but I would like to know what is the best approach if I have to deal with a larger array, and especially if I do not know the max size in advance...
Here it is my solution, and the VI.
thanks!
ps: i renamed the VI extension from vi to vit to trick the buggy uploader...

The case statement can be removed. Your for loop is auto-indexing the array so all you do is place the function inside it. The case statement is just not required.
Dennis, I think you misunderstood the issue. I thought the same thing until I realized what they are doing. Think of reading a single sample from 11 channels using DAQmx. Now perform a standard deviation on each of the channels over time. This is a tough one. I'm not sure how I would handle it differently.

Arrays-Neighbouring elements

I'm stuck:( I'm currently workind on a project for school. I'm trying to construct a method that determines if two elements in my array(String[][]) are neighbours(beside, above or below). I tried placing the elements into a vector and then if their difference is 1 the condition would be true. If anyone understands my ramblings can you please help me!!!

Each element is designated as such array[y][x]
a = the absolute value of x1 - x2
b = the absolute value of y1 - y2
if a == 1 and b == 0 OR a == 0 and b == 1 the elements are neighbors.

How to declare value binding to array list element in a pojo?

I have a POJO called P, that contains an ArrayList member called w.
class P {
private ArrayList w = new ArrayList(5);
w is initied in the class constructor.
The POJO is in the SessionBean and I would like to reference individual
elements in the ArrayList via a value binding like so;
#{SessionBean1.instanceOfP.w[5]}
I'm not sure how to declare the getter/setter for member W in POJO P
so that setter and getter injection work.

You may not be able to directly set the indexed value.
Try some thing like this.
Add a property that returns the indexed value.
Ex. if you ArrayList objets are of type "String"
int index = 5;
public String getMyValue(){
return w.get[index]
Now your value binding would look something like
#{SessionBean1.myValue}
BTW, if you want to access different index, create another method
public void setIndex(int index){
this.index = index;

Array of elements

Hi, i want to create a n-dimensional array full of data (string type). Something like attached file but a bit more advanced. I need to use while loop. Every time the column,row and input data change.
It would look like this:
first time a start while loop the input data should go to col 1, row1
second time input data to col 4, row 7
third to col 6, row 22,
and so on... i thking you understand the point.
in attached file i want to write string in every row.
Thanks for the answer,

Build array of elements in a for loop

Hello, I have a program where I am taking voltage measurements and computing resistances inside of a for loop. I then want to take these values an place them in individual arrays which are then sent to another subVI to compute the mean and standard deviation. Currently it appears the arrays are getting overwritten and only one value is stored in the array. Please let me know what I have to do to fix this. Thank you.
I have attached my VI and the area I am talking about is in the case statement inside the big for loop for case 1.

The image shows two possibilities:
Still, you should really simplify your data structures. For example you could have all your 7 results as a single 1D array and built it as a 7xN 2D array, etc. You probably can reduce the clutter on the diagram by 90%!
It is a nightmare to deal with subVIS containing so many individual connectors.
