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
