Compute slope aspect and curvatures
Computes slope, aspect and curvatures (depending on cond1, cond2) for derivative arrays adx,...,adxy between columns ngstc and nszc.
| ngstc | starting column |
| nszc | ending column |
| k | current row |
| c2max | min,max interp. values |
| cond2 | determine if particular values need to be computed |
