Please see the MATLAB code and equivalent Numpy code below. Question: How can I get the D variable same in Numpy as MATLAB's?
MATLAB Code
A = [1 2 3; 4 5 6; 7 8 9]C = [100 1; 10 0.1; 1, 0.01]
C = reshape(C, 1,3,2)
D = bsxfun(@times, A, C)
D(:,:,1) =
100 20 3 400 50 6 700 80 9
D(:,:,2) =
1.0000 0.2000 0.0300 4.0000 0.5000 0.0600 7.0000 0.8000 0.0900
Numpy Code
A = np.array([[1,2,3],[4,5,6],[7,8,9]])C = np.array([[[100, 1], [10, 0.1], [1, 0.01]]]) # C.shape is (1, 3, 2)
D = A * C.T
D
array([[[100. , 200. , 300. ], [ 40. , 50. , 60. ], [ 7. , 8. , 9. ]], [[ 1. , 2. , 3. ], [ 0.4 , 0.5 , 0.6 ], [ 0.07, 0.08, 0.09]]])
