import numpy as np >>> x, y = np.arange(1,5).reshape(2,2), 3*np.eye(2) >>> x, y >>> x, y = np.arange(1,5).reshape(2,2), 3*np.eye(2) >>> x, y (array([[1, 2], [3, 4]]), array([[3., 0.], [0., 3.]])) >>> x + y # element-wise addition ...
Element-wise multiplicationis where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using themul()function: o...

Hi all, I have been looking for an MKL version of elementwise matrix multiplication that works based on a condional approach.While Vmult can be used
Where it tries to do matrix multiplication, but if this has a dimension mismatch fails it just coughs up the value error seen. I'll try to patch this tomorrow by falling back on pointwise multiplication when there is a dimension mismatch, like the ndarrays do. In [8]: np.multiply(A, ...
How do I perform element-wise multiplication for vector X (size n x 1) with each polynomial features, p such as X_p(i) = [X(i) X(i).^2 X(i).^3 ... X(i).^p], where i is each row of X, so that the result will return with a matrix of size (n x p)...
Such an element-wise multiplication would result in a matrix, and not in a scalar. I know that there is a "dot" in there, but I would also add a summation sign, or at least mention that the operator is a dot product which results in a scalar. ludwigschubert assigned colah Nov 20,...
