How to solve
Each output component is one row of the matrix dotted with the vector.
Steps
- Dot the first row with the vector for the first component.
- Dot the second row for the second component.
- Write the result as a vector.
Example
[[2, 1], [0, 3]] times (4, −1)
- Row 1: 2·4 + 1·(−1) = 7.
- Row 2: 0·4 + 3·(−1) = −3.
