Multiply each row in a matrix by a row vector [duplicate]

Question

I have a matrix A of size r x c, c is constant but r can vary. I have a row vector of length c.

I need to produce a matrix which is product of multiply each row in A by the row vector.

I have tried

new_matrix = A * row_vector

but it returns an error because they aren't the same shape.
