procedure LogRamp(const RampVec: TVec; StartPower: Double; StopPower: Double);
Compute a logarithmic ramp.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | RampVec | TVec | |
| 2 | StartPower | Double | scalar |
| 3 | StopPower | Double | scalar |
Result: stored in self (calling object)
Remarks:
Fills RampVec vector with (base 10) logarithmic scale values from StartPower to StopPower. The number of values returned is defined with RampVec.Length.
