Are you sure you don't mean dimensions 3 x 1 and 1 x 3? There must be at least one row and/or column in a matrix.

You can multiply a m x p and a p x n matrix and the result will be a m x n matrix, but m,p, and n must be natural numbers.

I can't visualize a 3 x 0 matrix.

It must have 3 rowns but zero columns, so where are the entries??
