Dear Pat,

mat2cell is the only easy solution for your question. You are getting this error because your the mod of your IMG and 10 is not equal to zero. In other words the dimensions of IMG can't be evenly divided by 10. so either you take image of size whose dimensions are divisible by 10. Example:

IMG = magic(100);
IMGcells = mat2cell(IMG, 10*ones(1,size(IMG,1)/10), 10*ones(1,size(IMG,2)/10));

so make sure your image dimensions are divisible by 10, or any grid size you want.

IMGcells = mat2cell(IMG, 10*ones(1,size(IMG,1)/10), 10*ones(1,size(IMG,2)/10);
