Description
The formula 'MultiplyMatrixVector' returns the product of a matrix and a vector. The formula 'MultiplyMatrixVector' multiplies the rows of the vector with the columns of the matrix. The elements of the first column of the matrix will be multiplied by the first element of the vector, the elements of the second column of the matrix will be multiplied by the second element of the vector and so on. The number of rows of the vector has to be of the same size as the number of columns of the matrix.
Parameters
Matrix: the matrix you want to use for multiplication with a vector.
Vector: the vector you want to use.
