multiplication of matrix with blocks of an image ( 3 channel)

I divided an image into 8x8 blocks using mat2cell() . result was 'i' number of 8x8 matrices , say M{i} , with each M{i} in turn having 3 8x8 matrices say , ans(:,:,1) , ans(:,:,2) and ans(:,:,3) ( corresponding to 3 channels RGB of the image ). Now I need to apply haar wavelet transform ( H-matrix) on each block ( 8x8 H matrix is already available ) and I need to store the resulting matrices in another cell array if possible . To do this , when I use H*M{i} , I get the following error : " MTIMES is not fully supported for integer classes. At least one input must be scalar.To compute elementwise TIMES, use TIMES (.*) instead." I want to perform matrix multiplication and not element wise . Any help on this is greatly appreciated . Thanks.

You can make your question more readable. Just describe the nature and the size of your matrix, then ask what kind of operation you want to achieve.

a=randi(5,2,2,3)
b=randi(5,2,2,3)
c=a.*b
