Matrix Demonstration
Intuition
: The element in the i-th row and j-th column of the result matrix C. : The element in the i-th row and k-th column of A. : The element in the k-th row and j-th column of B.
Widths and Heights
- i: Corresponds to the height of A (its rows) and is used to determine the rows of C.
- j: Corresponds to the width of B (its columns) and is used to determine the columns of C.
- k: Corresponds to the width of A (or the height of B), which must be the same for multiplication to be defined.
