Specifically, we design a generative model that learns a latent space of diverse matrix... Web30 May 2024 · A permutation matrix is another type of orthogonal matrix. When multiplied on the left, an n -by- n permutation matrix reorders the rows of an n -by- n matrix, and when multiplied on the right, reorders the columns. For example, let the string 12 represent the order of the rows (columns) of a two-by-two matrix.
