Since you aren't very descriptive with your question, I would simply suggest reading up on Matrix Concatenation from the documentation:

A surprising question. If you want to concatenate two matrices horizontally:
C = [A, B];
And vertically:
C = [A; B];
Perhaps you have a more complicated problem to solve?! Are you talking of a large cell vektor containing a lot of matrices and suffer from CAT, which fails to use an efficient pre-allocation method?
