How do you multiply a vector and a matrix in C++?
The function multiply(vector,vector) takes two Vectors, A and B as arguments and returns 2D-Vector as multiplication result. If the dimensions of A and B are incompatible for multiplication it returns a Null Vector. The first line of input takes dimensions of Vector A. Then it asks for the elements of A.
Can you multiply a matrix with a vector?
To define multiplication between a matrix A and a vector x (i.e., the matrix-vector product), we need to view the vector as a column matrix. We define the matrix-vector product only for the case when the number of columns in A equals the number of rows in x.
We call Ax a product and use multiplicative notation for reasons that will become clear shortly. We can only multiply an m × n matrix by a vector in Rn. That is, in Ax the matrix must have as many columns as the vector has entries. If we multiply an m × n matrix by a vector in Rn, the result is a vector in Rm.
