pascal - Pascal matrix
Syntax
A = pascal(n)
A = pascal(n,1)
A = pascal(n,2)
Description
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 pascal(n,1). A is
a cube root of the identity matrix.
Examples
pascal(4) returns
1 1 1 1
1 2 3 4
1 3 6 10
1 4 10 20
A = pascal(3,2) produces
A =
1 1 1
-2 -1 0
