A Brief Primer on Matrix Algebra
... plication, one must follow a row-by-column rule that strictly dictates how the multiplication is performed. This will be demonstrated shortly. Because this row-by-column rule governs matrix multiplication, only matrices with certain eligible dimensions can be multiplied. Specifically, the columns o ...
