Pytorch matrix square root

WebMar 18, 2024 · PyTorch rsqrt () method computes the reciprocal of the square root of each element of the input tensor. It accepts both real and complex-valued tensors. It returns ‘ NaN ‘ (not a number) as the reciprocal of the square root of a negative number and ‘ inf ‘ for zero. WebJun 13, 2024 · we can compute the inverse of the matrix by using torch.linalg.inv () method. It accepts a square matrix and a batch of the square matrices as input. If the input is a batch of the square matrices then the output will also have the same batch dimensions. This method returns the inverse matrix. Syntax: torch.linalg.inv (M) Parameters:
