You can use the mat2cell command to subdivide the matrix. For this particular case, please refer to the following code snippet. Please make sure that your inputSqMat is exactly divisible into the subDivisions
function out = cropping(inputSqMat, subDivisions)
lengthSqMat = size(inputSqMat,1);
subDivisionVect = subDivisions*ones(1, lengthSqMat/subDivisions);
out = mat2cell(inputSqMat, subDivisionVect, subDivisionVect);
To access a particular element, you can index into the variable. For example:
out{1,1}

See the FAQ for two ways to do it, one using cell arrays, and one not.
