How to implement numpy broadcast mechanism with mkl?
I have been confused, how to use mkl to efficiently implement the broadcast mechanism in numpy ((Element wise operator "+","","*")?
such as
2D array sub 1D array
[[1,2,3],
[4,5,6],
[7,8,9]]

[1, 2, 3]
=
[[0, 0, 0],
[3, 3, 3],
[6, 6, 6]]
And the second operation (can be understood as a matrix multiplied by a diagonal matrix)
2D array multiply 1D array(Element wise multiply )
[[1,2,3],
[4,5,6],
[7,8,9]]
*
[1, 2, 3]
=
[[1, 4, 9],
[4, 10, 18],
[7, 16, 27]]
