WebJan 22, 2024 · The matrix multiplication is an integral part of scientific computing. It becomes complicated when the size of the matrix is huge. One of the ways to easily compute the product of two matrices is to use methods provided by PyTorch. This article covers how to perform matrix multiplication using PyTorch. PyTorch and tensors: Webtorch.matmul(input, other, *, out=None) → Tensor Matrix product of two tensors. The behavior depends on the dimensionality of the tensors as follows: If both tensors are 1-dimensional, the dot product (scalar) is returned. If both arguments are 2-dimensional, the matrix-matrix product is returned. dpf doctor thornton fife
