Start, Stop, Step Sweep Parameter Strategy

Use the Start, Stop, Step strategy with the Sweep Loop step to specify a range of values to sweep over. When the Start, Stop, Step strategy is selected for a sweep parameter, the following additional options are available:

  • Start —Specifies the first value for the sweep.
  • Stop —Specifies the ending limit for the sweep. The Stop value may or may not be included in the sweep depending on the Start and Step values.
    Note A Stop value without an exact floating point representation may fall outside the specified range if the direction of the sweep is reversed. You may need to modify fractional Stop values to accommodate the specified range.
  • Step —Specifies the step size for the sweep.
  • Distribution —Select Linear or Geometric Progression to specify how to distribute the sweep points. If Linear is selected, the Step value is added to the current value to calculate the next sweep value. If Geometric Progression is selected, the current value is multiplied by the Step value to calculate the next value.

The table below displays examples of sweep settings.

Start Stop Step Distribution Sweep Parameter Values
1 5 1 Linear 1, 2, 3, 4, 5
0 100 40 Linear 0, 40, 80
5 1 -2 Linear 5, 3, 1
1 INF 100 Linear 1, 101, 201, 301, 401, ...
1 1000 10 Geometric Progression 1, 10, 100, 1000
20 3 0.5 Geometric Progression 20, 10, 5
1 INF 100 Geometric Progression 1, 100, 10000, 1e6, 1e8, ...

Sweep parameter values may have any numeric representation. The representation of the Start option defines the representation for the sweep. The Stop and Step options must have the same representation as Start.
