Identity matrix: intro to identity matrices (article) - Khan Academy

WebThe n\times n n×n identity matrix, denoted I_n I n, is a matrix with n n rows and n n columns. The entries on the diagonal from the upper left to the bottom right are all 1 1 's, and all other entries are 0 0. The identity matrix plays a similar role in operations with matrices as the number 1 1 plays in operations with real numbers. WebJan 20, 2024 · To create an identity matrix, we use the torch.eye () method. This method takes the number of rows as the parameter. The number of columns are by default set to the number of rows. You may change the number of rows by providing it as a parameter. This method returns a 2D tensor (matrix) whose diagonals are 1's and all other elements are 0.
