WebApplying torch.diag_embed() to the output of this function with the same arguments yields a diagonal matrix with the diagonal entries of the input. However, torch.diag_embed() has different default dimensions, so those need to be explicitly specified. Parameters: input – the input tensor. Must be at least 2-dimensional. WebThe 3-input form returns a diagonal matrix with vector v on the main diagonal and the resulting matrix being of size m rows x n columns. Given a matrix argument, instead of a vector, diag extracts the k -th diagonal of the matrix.
