CHOLDC is based on the routine choldc described in section 2.9 of Numerical Recipes in C: The Art of Scientific Computing (Second Edition), published by Cambridge University Press, and is used by permission.
Note: If you are working with complex inputs, use the LA_CHOLDC procedure instead.
CHOLDC, A, P [, /DOUBLE]
An n by n array. On input, only the upper triangle of A need be given. On output, L is returned in the lower triangle of A, except for the diagonal elements, which are returned in the vector P.
Note: If CHOLDC is complex then only the real part is used for the computation.
An n-element vector containing the diagonal elements of L.
Set this keyword to force the computation to be done in double-precision arithmetic.
