Array of 50 elements

hi! i just need a little help, i really dont need the whole program jus the important methods of it.
Searching Array of 50 elements out of the 50 Integer Value in your Array,
the user can enter a value & your program will display the specific
subscript/index that contain the value
All computation must be place in a method that returns a value.

Best Way To Build An Array Of Many Elements

Simple question for you LabVIEW experts: I want to build an array of many element for use in my code. The problem is I have 20 elements I need to insert into the "Build Array Function." This takes up much code space and is really not that clean. I was thinking of using a For Loop and use the iteration terminal as the index for each element. The For Loop would then use auto indexing and build this array for me.
Is there a more efficient way to do this? Thanks!

Crossrulz, I was planning on handling it like this:
I have a total of 17 element I need to build an array from. Each case would include another element to be written to the array. Is this the correct way to handle this?
Thats one way to do it. Not nearly as efficient as using the Build Array, but it will work.

Indexing array of references element by element

Hello,
I have a simple question. How do I go about indexing an array of references element by element? For example, when using a cluster reference, there is a property node called "controls [ ]" that we can pass into a for loop. For a normal array, "enable indexing" is usually automatically turned on when entering a for loop. Why is it that for an array of references, this is not the case? Thanks for the help.
Solved!

Since the Get Image is a method, it has to work on something, and that would be a picture control or indicator. (If you look at the Get Image Method for the array, you'll notice it only returns an image of the front panel object, so I think you'd just get a picture of the array as it looks on the FP).
So you'd send the picture to an indicator, then use the Get image method on that indicator immediately afterwards. See attached. I didn't try this out so I can't be sure it would work, but I think it would. But it would still be a major hack compared to just using the Picture to Pixmap VI.

"How would I add the rows of a 640 x 240 2D array together? I mean , the elements of row 1 to the element of row 2 and so on. I want to end up with a 1 d array of 640 elements in which each element is the sum of the other 240 elements in the rows."

"For explaination , like this
1 1 1 1 1 1 1 ....... to 640
+2 2 2 2 2 2 2 .......
+3 3 3 3 3 3 3 .......

Appreciate the sample VI's but I can't open them ( I have Labview 5.01 )

Here is Mikael solution, expanded to include rows and ready to use as a subVI. Now all is needed is the polymorphic version

How to create array with "n" elements...

Hy, how can i create a array with "n" elements ?

i know, but the thing is: the other methode (which
one isn't developed fom me) needs an Object Array
(Object []) to work correctly...then take a look into the method toArray() of the Collection interface.
thats why i need this gay "object Array"....I think it would be wise to avoid that adjective in this context and meaning.

Sort array with equal elements

Hi, I'm a new one.
I have a problem to sort 2d array with equal elements (it has 5000000 of elements from 1-255) for example:
1 2 1 1 3 4 5 5 6 1 2 3 (value from 1-255)
2 2 1 1 3 3 3 3 4 4 4 1 (value from 1-255)
And I need make array or matrix 255 rows vs 255 colomns, and count how many equal elements for example:
1 2 3 4 5 6
1 0 1 0 1 0 0
2 0 1 0 1 0 0
3 1 0 1 0 0 0
4 0 0 1 0 0 0
5 0 0 2 0 0 0
6 0 0 0 1 0 0
I'll be happy if someone could help me

I understand that it's very complicated explain.
I build 2d array from two 1darray each of them has values 1-255. So right now i must constract array or matrix 255x255 where must calculat how many times value from (1-255) for one array in another array and write this sum for each value 1-255. I try to show it
1 2 so I need array 3x3; for first row for value 1 I have two times value 3 and one time value 2
2 2 2 I have two times value 1 and one time value 2 and one time value 3
3 2 3 I have two times value 2 and one time value 3
3 2 so my result matrix will be 1 2 3
3 3 1 0 1 2
2 3 2 2 1 1
2 1 3 0 2 3
2 1
1 3
1 3
Maybe its more clear

Why does Read from Text file default to array of 9 elements

I am writing to a text file starting with a type def. cluster (control) of say 15 dbl numeric elements, that works fine I open the tab-delimited text file and all of the elements appear in the file. However when I read from the same text file back to the same type def. cluster (indicator), the read from text file defaults to 9 elements?? Is there a way to control how many elements are read from the file. This all works great when I initially use a cluster of 9 elements and read back to a cluster of 9 elements.
Solved!

From the LabVIEW Help: http://zone.ni.com/reference/en-XX/help/371361G-01/glang/array_to_cluster/
Converts a 1D array to a cluster of elements of the same type as the array elements. Right-click the function and select Cluster Size from the shortcut menu to set the number of elements in the cluster.
The default is nine. The maximum cluster size for this function is 256.
Aside: so, how many times has this question been asked over the years?

Store XML node value into an array with node element name

Hi,
I have the following code that displays the node element with the
corresponding node value. I want to store the values in an array in
reference to the node name.
i.e.
XML (my xml is much bigger than this, 300 elements):
<stock>
<symbol>SUNW</symbol>
<price>17.1</price>
</stock>-----
would store the following:
*data[symbol] = SUNW;*
*data[price] = 17.1;*
Thanks in advance,

I still need to store it in an array because its 300 elements in the XML stocks.

How to create an array of indefined elements

Hi. I need to write a program that store n number of elements in an array. The program have to ask the user to input some values, and it stops until the user says that he dont want to input more values.
I have the following code:
public class Controlador{
private Contacto[] lista;
private int contactoActual;
private int continuar = 0;
private Interfaz interfaz = new Interfaz();
public Controlador(){
    lista = new Contacto[contactoActual];
    contactoActual++;
public void insertarContacto(){
    do{
      Contacto persona = new Contacto();
      persona.insertarNombre();
      persona.getNombre();
      persona.getTelefono();
      contactoActual++;
      lista[contactoActual] = persona;
      continuar = interfaz.mostrarContinuar();
    }while(continuar==1);
}with this, I got an array out of bounds exception.
Can somebody help?
regards.

Yes and no.
Once you have created an array you cannot change its size. So if you create an array of size 10 and user wants to input 11 numbers, your progrm will crash. Hoever you can get around this by checking the size of the array before inserting. If the array is full, create another array that is bigger, copy all values from original array to new array and then insert the new number. All this requires a lot of work. Use a Collection such as an ArrayList so you don't have to worry about the size.

React on Array's last Element arrival

Hello NI developers!
My VI reads data from board and fills array. As data acquisition speed is slower than VI performance I want VI react and perform action exactly when array gets it's last element. I don't want to use Stacked Sequence Structure, because there NEXT frame executes only when it gets all the data from previous frame and if I manipulate large amounts of data (i.e. Megabytes) it will be hanging somewhere in memory. I want to catch that moment when array filled with last element. Any advices how can I reach that?
Thank you in advance.
Message Edited by ACiDuser on 06-26-2008 08:17 AM

I want calculate transfer speed. CIN measures time that takes FOR Loop and sends it to LV. And I get this time with microsecond precision. I got an idea... Maybe I should use this Stacked Event Structure only for "Time" indicator.. and inside Check If it's not equal with 0 then - calculate speed!

Boolean array from Vector element

I have a Vector with each element being a boolean array. When I use the elementAt method it returns an object which I have to then cast in some way to a boolean array.
Is this possible?
Thanks for your help,
Wallace

By the way:
- don't use Vectors if you don't have to. Other collections may be better suited and faster.
- if you use Java 1.5, use Generics. Then you won't have to cast anymore.

Initialise waveform array of 10 elements

Hi all,
I would like to create an array of 10 waveform datatype constants to pass into a structure. Once passed in, 9 of these elements will be extracted and then another added after which the new 10 will be graphed. Hopefully this will effectively create a continuously updating graph of my data.
I was wondering if anyone knows how to create a 10 element array using waveform datatypes.
I look forward to the great help I have received so far.

Hi,
The charts are a bit limiting as I would like to see the grid lines so that values can be directly read from the graph. What I am trying to do is to acquire some data from a liquid nitrogen tank we have and then display it on a graph so that we can see the last four days usage. This is important for us as if we run out our experiments will fail.
The only way I can think of doing this is to create a 10 element array and feed it through a shift register into a while loop. Inside the loop the array will be cut to 9 elements using the subset array function and then the new data point that is acquired will be added to the array. This would make the new array one point different each time. Each time the array is appended it would be redrawn effectively showing a continuously acquiring graph. The obviously the shift register would feed the new array back into the beginning and it would update again.
I have tried many iterations but there always seems to be a problem.

I am trying to design a VI that will identify the position of any overshoots and undershoots from an input array of 100 elements

I am trying to design a VI that will identify the position and number of all overshoot and undershoot values. I have been trying for the past three weeks to solve this problem but I am having difficulty with the output arrays which will store the overshoot/undershoot values. I am using a for loop but when I connect the array indicator the wire from the o/p tunnel to the array indicator shows an errror? Any help would be greatly appreciated
Regards,
Kadeel

Hi Kadeel,
what error do you get? What happens when you right-click the loop output and select Create->Indicator?
Why not attach your vi, that you have been working on for 3 weeks?
