probably you can use
mat2cell
IMO splitting a matrix in cell is rarely a good idea if you want your code works decenly in speed.

There is not enough information to be certain about your question, but by addressing your matrices you can create submatrices like this:
BigMatrix = ones(16,16,16);
smallMatrix_1 = BigMatrix(1:8,1:8,1:8);
smallMatrix_2 = BigMatrix(1:8,1:8,9:16);
smallMatrix_3 = BigMatrix(1:8,9:16,1:8);
smallMatrix_4 = BigMatrix(9:16,1:8,1:8);
etc.
