2. how to multiply 2 numpy array with different dimensions

   stackoverflow.com/questions/40267131

   If you wish to multiply X of dimension (n) to Y of dimension(n,m), you may consider the answers from this post Tips can be found in the Wikipedia as well: In Python with the numpy numerical library or the sympy symbolic library, multiplication of array objects as a1*a2 produces the Hadamard product, but with otherwise matrix objects m1*m2 will ...

3. Multiply two matrices with different dimensions in R

   stackoverflow.com/questions/63449609

   What I want is to multiply each row of one matrix for each row of the other matrix and obtain this: > zz [,1] [,2] [,3] [1,] 10 20 30 [2,] 400 500 600 I have tried sapply(yy, function(x) xx*x) which produces a 6x2 matrix instead of the 3x2 matrix I want.

4. Multiplying matrices with different dimensions - Stack Overflow

   stackoverflow.com/questions/41134393

   I have two matrices with different dimensions that I would like to multiply using einsum numpy: C(24, 79) and D(1, 1, 24, 1). I want to obtain the matrix with the dimension (1, 1, 79, 1). I have tried to multiply them in two ways:

5. Multiply two matrices with different dimensions python

   stackoverflow.com/questions/71734851

   1. I am assuming you wish to perform matrix multliplication. This cannot be achieved if the dimensions of the matrices are different. You can achieve the desired result by using reshape and numpy.matmul(). Code: import numpy as np. x1 = 3-7/3; x2 = 2-4/3; x3 = 1-5/3;

6. Multiplying large matrices with different dimensions with numpy

   stackoverflow.com/questions/59147017

   I have tried the following to multiply the matrices and used smaller numbers to verify the multiplication: result = np.dot(matrix1,matrix2) result = matrix1.dot(matrix2) result = np.multiply(matrix1, matrix2[:, None]) These three ways do work when the dimensions of both matrixes are equal to each other. So, a 5 * 5 matrix multiplied by a 5 * 5 ...

7. Multiplying two matrices with different dimensions

   stackoverflow.com/questions/10163948

   I am writing an application to multiply matrices. This works nicely as intended for matrices a and b that are nxn: for(k = 0; k < n; k++) { for(i = 0; i < n; i++) { tmp = a[i][k]; for(j = 0; j < n; j++) { c[i][j] = c[i][j] + tmp * b[k][j]; } } } If a was nxy and b was yxm (implying c to be nxm).

   stackoverflow.com/questions/43439245

   I have a matrix multiplication function defined as shown below: void mat_mult(array <array <float, 3>, 23>& a, array <array <float, 23>, 3>& b, array <array <float, 3>, 3>& c); The function call is such that matrix mat1 will be a, mat2 will be b and matrix c will store the result of a * b. My understanding is that I will need to create a ...

10. Multiplying matrixes of different dimensions in Python

    stackoverflow.com/questions/69423811

    Matrix 1 and 2 have dimensions 2x3, and 3X5. Both have 1 dimension of 3, thus the output matrix is 2x5. Your matrixes are 4x4, and 1x2. I do not understand what matrix C has. Basically I am saying you cannot multiply these matrices together because of their dimensions. –

    stackoverflow.com/questions/47535972

    This works perfectly, but only if I multiply matrices with the same dimensions (e.g. Mat4x4*Mat4x4 or Mat2x4*Mat2x4). I understand I can't just multiply an Mat4x4 with an Mat9X2 or anything, but I do know the second matrix's columns should be equal to the first matrix's rows (so a Mat2x2 should be able to multiply with a Mat2x1) and that the ...
