A = pascal(n) A = pascal(n,1) A = pascal(n,2)
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.
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 = 0 0 -1 0 -1 2 -1 -1 1
