Matrix decomposition with extended diagnostics
Parameters:
KSYM Input/output-integer-default=1.
1 Use symmetric decomposition (default).
0 Use unsymmetric decomposition.
-1 Use decomposition consistent with form of [A]. KSYM will be
reset to 0 or 1 consistent with actual decomposition type.
3 Use symmetric partial decomposition.
CHOLSKY Input-integer-default=0. If KSYM=1 or KSYM=-1 and [A] is
symmetric then:
1 Use Cholesky decomposition.
0 Use standard decomposition (default).
If KSYM=3, then CHOLSKY is set to the number of degrees of freedom
in the o-set.
BAILOUT Input-integer-default=0. If BAILOUT>0, then the module exits with
error message if factor to diagonal ratio exceeds MAXRATIO. If
BAILOUT
