problem of creating a matrix using the calculated cooccurrence matrix features;

these are the steps of my programme

1. read the original image
2. sub divide the image to 4096 bloks of 4*4( mat2cell() )
3. for each sub image apply the graycomatrix() and graycoprops(I,'Contrast')
4. for each sub image it gives the answer like this contrast: 23
5. now I want to input all the 4096 values into single matrixif you know the answer pls help me.

Just index an array in the loop

allTheContrasts = zeros(1, numberOfBlocks); % Initialize
for k = 1 : numberOfBlocks
  % Calculate contrast via graycoprops or whatever.
  thisContrast = .......
  % Then save this block's contrast into an array.
  allTheContrasts(k) = thisContrast;
end
