Function Reference
— Function File: pascal (n, t)

Return the Pascal matrix of order n if t = 0. t defaults to 0. Return lower triangular Cholesky factor of the Pascal matrix if t = 1. This matrix is its own inverse, that is pascal (n, 1) ^ 2 == eye (n). If t = 2, return a transposed and permuted version of pascal (n, 1), which is the cube-root of the identity matrix. That is pascal (n, 2) ^ 3 == eye (n).
