How do I count the number of 1's in a Boolean Array??

I have a boolean array of 1000 0's or 1's and want to know the number of times this array is in the 1 position.
The array is repeated within a structure and i need a number for each iteration to be passed onto the next (using a shift register).
Never really used boolean arrays before so none of the standard things i use seem to work?
Thanks in Advance.
Ross

Ross,
The quick easy way is to convert the boolean array to a 0-1 array from the boolean menu, then sum the array using "sum array elements" from the numerical menu.

How can i count the number of data patches in a numeric array

Hi All

BobLondn wrote:
Can I build a 2d array where I can store on one column the index of each data patch and on the second column to store the length of elements of relevant data patch.
Here's a quick example (LabVIEW 9.0) that stores the start index and length of all negative patches in a 2D array.

How do I count the number of records returned in the CMIS query

How do I count the number of records returned in the query CMIS?
SELECT COUNT(*) FROM ora:t:IDC:GlobalProfile WHERE ora:p:xRegionDefinition = \'RD_PROJETOS_EXCLUSIVOS\''}
Euler Homero

Hi Euler,
interestingly enough, the reference guide for CMIS ( http://wiki.alfresco.com/wiki/CMIS_Query_Language ) that I found does not mention the COUNT function at all. On the other hand it states that: "The SELECT clause identifies which virtual columns to return in the result set. It can be either a comma-separated list of one or more queryNames of properties that are defined by queryable object types or * for all virtual columns."
There are, however, some other posts like e.g. http://alfrescoshare.wordpress.com/2010/01/20/count-the-total-number-of-documents-in-alfresco-using-sql/ which state that they could make it working.
Having asked in the WebCenter Portal forum, I assume that your content repository is WebCenter Content. The CMIS doc for the Content is available here: http://docs.oracle.com/cd/E23943_01/doc.1111/e15813.pdf (no COUNT there either). It does, however, mention explicitly that "CMIS queries return a Result Set where each Entry object will contain only the properties that were specified in the query.". This means your could rather investigate the Result Set. Note that there are also other means than CMIS how to get the requested result set (e.g. calling a search service directly via so-called RIDC).
In the given context I am also interested what your use case is. OOTB CMIS in WebCenter Portal is used, for instance, in Content Presenter, where it is content rather than "parameters" what's displayed.

Count the number of values in a two dimensional array

i am trying to figure out how to count the number of values in a two dimensional array.
numScores = student[i][j].length;This doesn't work, i am trying to find a way of counting the columns

Object[][] o;
int tot = 0;
for(int x = 0 ; x < o.length ; x++)
tot += o[x].length;
}If it's not a jagged array, however, this would be easier:
int tot = o.length * o[0].length;

thanks in advance..

Jverd, this has actually been answered, but due to an

How do I count the number of *'s in a string?

I need to count the number of * in a string of carakters. And the return the number. 0 for no *'s in the string 2 for two *'s in the string and so on.
It's probably quite simple but I can't figure out how!

How do I count the number of occurrences of a string within a group of cells?

Hello all, I'm trying to figure out how to count the number of times a child has completed certain tasks. Here is a sample of the data (it is highly simplified here, but contains what I hope is needed to answer my question):
Unnamed Table
Objective
John
Ann
Alex
Dave
Eric
20a 20b 20c
x
20a 20b 20c
x
20a 20b 20c
x
x
19b 20a
      x
       x
20c 21b 22
     x
What I am trying to do is count the number of times each child completed each objective - but I can't figure out how to go about splicing up the "objectives" fields for counting while still being able to compare them to whether or not the "child" has 'an x in the box' in that particular row.

If I read your example correctly, John's counts should be 2 for 20a, 1 for 19b, 20b and 20c, and 0 for any other objectives listed.
Here's an example that will work for your data set, assuming that any objective ma occur only once in each row of column A of the Main table. I've added an a to objective 22, but I think it is unnecessary, provided there is no objective 122, 221, etc.
This uses a two step process.
The table AUX extracts the objectives completed by each student, using the checkboxes in Main. Note that it also adds a space at the beginning and end of each string. This provides an extra character before the first objective code and after the last objective code in that row, used by the wildcard specification in the formula in the Summary table.
Formula:
Aux::B2: =IF(OFFSET(Data :: $A$1,ROW()-1,COLUMN()-1)," "&OFFSET(Data :: $A$1,ROW()-1,0)&" ","")
Fill right to the last column and down to the last row of Aux.
Summary uses COUNTIF to count the number of occurrences of each of the objectives listed in column A of that table.
Formula:
Summary::B2: =COUNTIF(Aux :: B,"=*"&$A2&"*")
Fill right and down as the previous formula.

Barry

How do I count the number of cells with a particular text in it?

I have a column with peoples name in each cell. I want to count the numbe rof times a persons name appears in the column. How do I do this? any help would be great ! thanks in advance.

Hi Evilhomer,
The function COUNTIF will do this. Here are two Tables on one sheet. Table 1 contains names in Column B.
Table 2 contains the names once only (in any order) in Column A, with a COUNTIF formula in Column B to count how many times a name occurs in Table 1.
The formula in Sheet 2, Cell B2 is:
=COUNTIF(Table 1 :: B2:B5,A2)
Enter the formula in B2 then copy down.
It is easier to create the two tables on one sheet. If you then want to move a table to another sheet, Numbers will convert the formulas to keep the references valid.
There are other ways to do what you want. Please reply if this is not what you want.
Regards,
Ian.

How can I count the number of unique cells?

I have a column in my spreadsheet that looks like this:
Date
Items
3/25
Item A
3/27
Item A
3/29
Item A
3/25
Item A
4/25
Item B
6/1
Item B
7/13
Item B
8/9
Item B
3/5
Item C
1/2
Item C
5/15
Item D
3/25
Item D
What I want is something that will list all the unique items that I have and count the number of times that Item shows up in my spreadsheet. For example, the results should look like this:
Item A: 3
Item B: 4
Item C: 2
Item D: 2
I thought for sure that I can do a chart in numbers and it would count the number of items but no, not so much.

I apologize. When I pasted the table in Numbers running in French the values of column B were treated as dates.
I leave the screenshot untouched because the contents of this column changes nothing to the calculations.
In cell D2 of the main table, the formula is :
=IF(ISBLANK(C),0,IF(COUNTIF($C$2:$C2,"="&$C2)=1,COUNTIF(C,"="&$C2)+(ROWS(A)-ROW( ))/100000,0))
Apply Fill Down
In cell A2 of table aux, the formula is :
=IFERROR(LARGE(main :: D,ROW()-1),"")
In cell B2 of table aux, the formula is :
=IF(A>0,LOOKUP(A2,main :: D,main :: C),"")
In cell C2 of table aux, the formula is :
=INT(A)
Apply Fill Down

How can I count the number of times a timed loop finished late?

I am getting occasional timing errors in a timed loop under windows XP and would like to count the number of errors, but I can't find a simple software counter vi

The timed loop has a terminal (boolean) to indicate if the previous iteration finished late. Just increment an integer shift register if this happens.
The attached shows a very simple demo (LabVIEW 7.1).

How do I count the number of times a word appears in a column?

What I have is a spreadsheet logging work history. Let's say the work location is "office", "home", or "travel" and I want to have a separate cell in another table for totals, count up the number of time each appears in the data for the year. So it would look like this:
Date
Location
sept 1
office
sept 2
home
sept 3
home
sept 4
travel
sept 5
office
sept 6
office
sept 7
office
sept 8
travel
sept 9
home
sept 10
office
Totals
Days
10
Office
5
Home
3
Travel
2
I just can't figure out how to develop the formula to put in the Totals column to make it work this way. If you can help me achieve this I'd really appreciate it!

Hi SpartanAntarctican,
Table 1 to record your locations
Date
Location
sept 1
office
sept 2

sept 3
home
sept 4
travel
sept 5
office
sept 6
office
sept 7

sept 8
travel
sept 9

sept 10

Table 2 to sum your locations
Totals
Days
10
Office
5
Home
3
Travel
2
In Table 2 the formula in B2
=ROWS(Table 1::A)−1
Minus 1 because there is a Header Row in Table 1.
In Table 2 the formula in B3 (and Fill Down)
=COUNTIF(Table 1::B,A3)
You can check this by adding 5 + 3 + 2 to arrive at 10
Or maybe delete Row 2 put the Days calculation into a Footer Row in Table 2
=SUM(B) .

How can I count the number of values in one column which answer to a condition in another column?

I'm using Numbers 3.2 and would like to count the names in a column which satisfy a condition in a different column. There are 3 "streams" through which these names have come to me, and I would like to easily identify how many have come from each stream. Any help?

Hi DirtyDawg,
COUNTIF is your friend here.
If your source is in column C and your streams are 1, 2 and 3:
=COUNTIF(C,"=stream1")
=COUNTIF(C,"=stream2")
=COUNTIF(C,"=stream3")
These need to be in a footer or header row or in a different column than C.
hope this helps,
quinn

How do i count the number of times a cell has been referenced by other cells' formulae?

Hello,
I have a spreadsheet of recipes and ingredients that use checkboxes to let me know which recipes I can make based on the ingredients I have on-hand, using a formula like this one: =IF(AND('Spirits' :: A42,Mixers :: A18,Mixers :: A41,'Spirits' :: A25 ),Table 3 :: $A$2,Table 3 :: $A$3). If I've checked all of the boxes for ingredients that are required for any one of my recipes, the cell that the formula is in returns something like "YES"; otherwise, it returns a blank. It works well enough, but I'd like to include a cell next to each ingredient with a formula that will look through the hundreds of recipes, which all use a formula like the one above, and return a count of the number of times the ingredient's cell is referenced in those formulas. That way, I'll know which ingredients are the most commonly used in my eclectic collection of recipes. I thought something like =COUNTIF('Recipes' :: A2:A343, "=A2") would work, but it doesn't look at the cell references in the formulas, so no, it doesn't work. Any ideas? I'm using Numbers 2.3

Hello
There's no formula to inspect other formula in Numbers. So what you asked cannot be achived in such a way you described.
A simple alternative method would be to build recipe-ingredient matrix as follows.
