Get number of occurrences of value in a specific position in matrix

Hi, I have simulated 10,000 matrices and am setting up a Chi-square test and want to count the number of times a value has appeared in a given location in the matrix. Each matrix has the dimension 101x19. How can this be set up??

For example,

A1=[1 2 3; 4 5 6];

A2=[2 2 3; 4 5 6];

A3=[1 2 3; 4 5 6];

then number of occurences of 1 in cell (1,1) is 2. Now I have 10000 matrices, each of dimension 101x19.

As you know the locations.....you have indices in hand.....pick those values......check with your value:

iwant = nnz(matrixvalues==val) ;

If you have flottant

tol = 10^-3 ;
iwant = nnz(abs(matrixvalues-val)<=tol) ;

This is very helpful, however some of the values are zero that I want to consider. There are 10000 matrices so 10000 cells to check for a specific value (integer).

you can go ahead with the above lines.

why ?
