CST 325 – Week 3 – Matrix Operations

This week we covered matrix operations and focused primarily on 3×3 and 4×4 square matrices. For this week’s assignment, we had to implement functions that would compute matrix by matrix multiplication (which, by the way, is only valid if the first matrix is r x n and the second matrix is n x c), vector by matrix multiplication (focusing on row vectors, which must be on the righthand side), as well as calculating the determinant, the inverse and transposition of a given 3×3 or 4×4 matrix. The 1Blue3Brown videos were very helpful this week in illustrating all of these concepts. I also found Desmos helpful.
