feiting, what are you really interested in knowing? Do you want to know which one is better?
I'd say geoscsape is more powerful, and it isn't too costly. Many of us still use mat-edit or build our own editors towards our liking.
Geoscape is definitly more powerful than mat-edit, although
1.) Mat-edit has been out way longer
2.) Mat-edit is free, so you get what you pay for.
Nonetheless, mat-edit is probebly the most used free matrix editor out there.
Can't go wrong with either of the products.
Power=Geoscape
Free=Mat-edit
A book? I hate book. Book is stupid.
