I try to multiply 2 matrix x,y with shape (41) and (41,6)
as it is supposed to broadcast the single matrix to every arrow in the multi-dimensions
I want to do it as :
x*y
ValueError: operands could not be broadcast together with shapes (41,6) (41,)
Not exactly sure, what you are trying to achieve. Maybe you could give an example of your input and your expected output. One possibility is:
import numpy as np
x = np.array([[1, 2], [1, 2], [1, 2]])
y = np.array([1, 2, 3])
res = x * np.transpose(np.array([y,]*2))
This will multiply each column of x with y, so the result of the above example is:
array([[1, 2],
[2, 4],
[3, 6]])
