How can I split e.g. a a1xb1xc matrix into non-overlapping (neighbouring) smaller matrices a2xb2xc?

probably you can use
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);
