A = pascal(n)
returns the Pascal matrix of order
n: a symmetric positive definite matrix with integer entries taken from Pascal's triangle. The inverse of
A has integer entries.
A = pascal(n,1)
returns the lower triangular Cholesky factor (up to the signs of the columns) of the Pascal matrix. It is involutary, that is, it is its own inverse.
A = pascal(n,2)
returns a transposed and permuted version of
A is a cube root of the identity matrix.
A = pascal(3,2) produces
