Web18 mrt. 2024 · Element-wise matrix multiplication Sometimes we want to do multiplication of corresponding elements of two matrices having the same shape. This operation is also called as the Hadamard Product. It accepts two matrices of the same dimensions and produces a third matrix of the same dimension. WebThis shouldn't happen with NumPy functions (if it does it's a bug), but 3rd party code based on NumPy may not honor type preservation like NumPy does. A*B is matrix multiplication, so more convenient for linear algebra. Element-wise multiplication requires calling a function, multipy(A,B).
