I have two matrices

fi = [[f1],           Nij = [[N11 N12 .......N1n],
      [f2],                  [N21 N22 .......N2n],
       .                            ...
       .                            ...
      [fn]]                  [Nn1 Nn2 .......Nnn]]

I want to multiply:

f1 to each element of the 1st row,
f2 to each element of the 2nd row,

and so on.

I.e. I want Xij = fi*Nij where fi is a column matrix and Xij & Nij is nxn matrix.

I tried using

import numpy as np

fi = np.linspace(1,5, num =5)
fi = np.asmatrix(fi)

def Xij(ai):
    Nij = np.ones((5,5))
    for i in range(len(fi)):
    for j in range(len(fi)):
        Xij[i,j] = ai[i] * Nij[i,j]
return Xij

Zij = Xij(fi)

It gives me this error TypeError: 'function' object does not support item assignment

Why? and how do I solve this?
