rgbImage = imread('image.jpg');
[rows, columns , numberOfColorBands] = size(rgbImage);
Greenlayer = rgbImage(:,:,2);
blockSizeR = 8;
blockSizeC = 8;
wholeBlockRows = floor(rows / blockSizeR);
blockVectorR = [blockSizeR * ones(1, wholeBlockRows), rem(rows, blockSizeR)];
wholeBlockCols = floor(columns / blockSizeC);
blockVectorC = [blockSizeC * ones(1, wholeBlockCols), rem(columns, blockSizeC)];
ca = mat2cell(Greenlayer, blockVectorR, blockVectorC);
when I run this code with image of size 512*384 It works ,but if I run it on other size the following error occur have anyone any idea for the solution of this problem please and here is the error msg
Error using mat2cell (line 107)
Input arguments, D1 through D2, must sum to each dimension of the input
matrix size, [1648 2336].'
ca = mat2cell(Greenlayer, blockVectorR, blockVectorC);
thanks...

You're doing it on a 3D full color image - that's why it says that. You should probably do it one color channel at a time. If you do that it should not complain.

you are right , When I ran it in separate script it ran ,but with the rest of the code this error occur I will check the rest of the code to see where the problem is.
