## Revision 1.19  2000/08/28 20:17:59  peterg
## Put in Winfried Neun's bug fix
## -- prevents segmentation violation using optimised gentran when matrix
## comtains a number
##
## Revision 1.18  2000/08/24 17:11:40  peterg
## Now optimises as well as segmenting - uses the SCOPE package
##
## Revision 1.17  2000/05/20 15:23:56  peterg
## Paramererised version of sm etc etc (using -parameter switch)
##
## Revision 1.16  2000/04/18 11:14:18  peterg
