Details:
The response to "help pascal" states:
-- Function File: pascal (N, T)
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'.
In fact, the result of pascal(N,1) is a lower triangular matrix with columns
of alternating sign. This result is correct in that it agrees with Matlab,
but it is NOT the Cholesky factor. The Cholesky factor has only positive
values on the diagonal. The matrix returned for T=-1 IS the Cholesky factor.
