Hi all, I have a simple task at hand. I want to compute an element-by-element multiplication of two matrices A and B. If use C = A*B it delivers the
Let us perform element-by-element multiplication of the vectors x and y and save the results in z. This produces the vector z=[1×4, 2×5, 3×6]=[4, 10, 18]. Suppose that we have the vectors a=[1, 2, 3] and b=[4, 5, 6]T. Let us perform matrix multiplication on the ...
By running the element-by-element matrix multiplication and division between the pixels matrix and the key matrix, the sequences of pixels are encrypted and decrypted. This algorithm shows such advantages as good security, simple calculation, and easy availability for programming. Furthermore, the ...

I therefore want to perform matrix multiplication on the matrices but element by element multiplication of the vectors inside, is this possible? e.g when multiplying M1*M2 where M1=[A B ; C D], M2=[E F; G H] and A-H are all vectors I want MATLAB to return ...

Matrix multiplicationis where two matrices are multiplied directly. This operation multiplies matrix A of size[a x b]with matrix B of size[b x c]to produce matrix C of size[a x c]. In OpenCV it is achieved using the simple*operator: ...
It looks like when np.multiply is passed an ndarray objects it first tries to do matrix multiplication on them, if this fails due to a 'dimension mismatch', it does pointwise multiplication (element by element). However when np.multiply is passed a spmatrix object it asks spmatrix.__mul_...
