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 ispascal (
n, 1) ^ 2 == eye (
n)
. If t= 2
, return a transposed and permuted version ofpascal (
n, 1)
, which is the cube-root of the identity matrix. That ispascal (
n, 2) ^ 3 == eye (
n)
.
