Pascal matrix

`A = pascal(n)`

A = pascal(n,1)

A = pascal(n,2)

`A = pascal(n)`

returns a Pascal's 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.
