Detailed Description

Taucs class for Clp Cholesky factorization.

If you wish to use Sivan Toledo's TAUCS code see

http://www.tau.ac.il/~stoledo/taucs/

for terms of use

The taucs.h file was modified to put

#ifdef __cplusplus extern "C"{ #endif after line 440 (#endif) and #ifdef __cplusplus } #endif at end

I also modified LAPACK dpotf2.f (two places) to change the GO TO 30 on AJJ.Lt.0.0

to

        IF( AJJ.LE.1.0e-20 ) THEN
           AJJ = 1.0e100;
        ELSE
           AJJ = SQRT( AJJ )
        END IF
