Is transpose only for square matrix?

Answer: Yes, you can transpose a non-square matrix. However, you just have to make sure that the number of rows in mat2 must match the number of columns in the mat and vice versa. In other words, if the mat is an NxM matrix, then mat2 must come out as an MxN matrix.
