matrix inversion routines controlled with command
set matrix xxxx command, options are names:
parsed in getset, sets name 

#include "typmatrx.h"
#include "matin1.h"
#include "linpack.h"
#include "dgeco.h"

matin1   TypMatrx.chMatrix, "matin1 "
linpack  TypMatrx.chMatrix, "linpack"  <== default set in zero.c
veclib   TypMatrx.chMatrix, "veclib "

C 2D arrays are the opposite of fortran, so not Roman Catholic
cr = alphabetical order
