Webtorch.dot torch.dot(input, other, *, out=None) → Tensor Computes the dot product of two 1D tensors. Note Unlike NumPy’s dot, torch.dot intentionally only supports computing the dot product of two 1D tensors with the same number of elements. Parameters: input ( Tensor) – first tensor in the dot product, must be 1D. WebSep 4, 2024 · Speeding up Matrix Multiplication. Let’s write a function for matrix multiplication in Python. We start by finding the shapes of the 2 matrices and checking if they can be multiplied after all. (Number of columns of matrix_1 should be equal to the number of rows of matrix_2). Then we write 3 loops to multiply the matrices element wise.
