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) ;
