See this snippet/example:

m = [1, 108, 297, 451, 108, 297, 42]
index = find(m == 1)
index = find(m == 108)
index = find(m == 108, 1, 'first')
index = find(m == 108, 1, 'last')
index = find(m == 297)

In the command window:

m =
     1   108   297   451   108   297    42
index =
     1
index =
     2     5
index =
     2
index =
     5
index =
     3     6

Or this:

count = int32(1 : 500);
index = find(count == 1)
index = find(count == 108)
index = find(count == 297)
index = find(count == 451)

i used count(1) count(108) count(297) count(451)

is this a right cammand

That does not make sense to me. That will give you the value of the "count" array at element 108. If that's what you want, fine, but I thought you were looking for the element at which count had the value of 108.

You may use 'find'.

fi = find(data == 1);

or

fi = find(data == 108);

....

Good luck!

Your comment is not helpful. We don't know why it does not work. Please give an example of how it's not working.
