Can we multiply two vectors of different dimensions
Can we multiply two vectors of different dimensions The *operator in matlab represents matrix multiplication. The most basic rule of matrix multiplication is that the number of columns of the first matrix must match the number of rows of the second. Let's say that I have two matrices, A and B, with dimensions MxN and UxV respectively.

How to Multiply Vectors - Scalar (dot) product ...

Solution: When we multiply a vector by a scalar, the direction of the product vector is the same as that of the factor. The only difference is the length is multiplied by the scalar. So, to get a vector that is twice the length of a but in the same direction as a, simply multiply by 2. 2a = 2 • (3, 1) = (2 • 3, 2 • 1) = (6, 2)
