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
