python iterate over arrays matrices

I am trying to create a new matrix(array)

a = [1, 2, 3]

b = [0, 1, 2]

where

C = [[1*0, 1*1, 1*2], [2*0, 2*1, 2*2], [3*0, 3*1, 3*2]]

I have been scouring the documentation in numpy but can’t find a function to satisfy this.

for i in a:
    c = np.multiply(a, b)
    for j in b:
        c = np.multiply(a, b)

Answer

You’re looking for numpy.matmul. You’ll need to make the vectors have two dimensions (with a size of one in one of the dimensions). For example:

np.matmul(np.array([[1],[2],[3]]), np.array([[2,3,4]]))
