Web26 iul. 2024 · I have an ndarray of N 1x3 arrays I'd like to perform dot multiplication with a 3x3 matrix. I can't seem to figure out an efficient way to do this, as all the multi_dot and tensordot, etc methods seem to recursively sum or multiply the results of each operation. I simply want to apply a dot multiply the same way you can apply a scalar. WebActually, repeated addition of a matrix would be called scalar multiplication. For example, adding a matrix to itself 5 times would be the same as multiplying each element by 5. On the other hand, multiplying one matrix by another matrix is not the same as simply multiplying the corresponding elements. Check out the video on matrix multiplication.
