Matrix Multiplication

In this video I go over matrix multiplication and the rules used in its definition. Multiplying 2 matrices, [A] and [B], is defined such that a third matrix is produced, [C], that has the same number of rows as [A] and the same number of columns of [B]. Note that the number of columns of [A] must be equal to the number of rows of [B]. Each entry in [C] corresponds to a row of [A] multiplied by a column in [B] and as outlined in the video.

This video was taken from my earlier video listed below:
