Diagonal method matrix
WebMay 23, 2024 · 16. If you're using a version of numpy that doesn't have fill_diagonal (the right way to set the diagonal to a constant) or diag_indices_from, you can do this pretty easily with array slicing: # assuming a 2d square array n = mat.shape [0] mat [range (n), range (n)] = 0. This is much faster than an explicit loop in Python, because the looping ... WebSep 16, 2024 · When a matrix is similar to a diagonal matrix, the matrix is said to be diagonalizable. We define a diagonal matrix D as a matrix containing a zero in every entry except those on the main diagonal. More precisely, if dij is the ijth entry of a diagonal matrix D, then dij = 0 unless i = j. Such matrices look like the following.
