Multiply the Matrices [[13,0,-30]]*[[0,15,-10]]
Problem
Solution
Identify the dimensions of the matrices. The first matrix is a
1×3 row vector and the second matrix is a1×3 row vector.Determine if multiplication is possible. Matrix multiplication
A×B requires the number of columns inA to equal the number of rows inB Conclude that the operation is undefined. Since the first matrix has 3 columns and the second matrix has only 1 row, the dimensions do not align for standard matrix multiplication.
Note that if the second matrix was intended to be a column vector (
3×1 , the dot product would be calculated as(13×0)+(0×15)+(−30×−10) However, as written, they are both row vectors.
