num_steps


Number of sampling steps along the vector in a vector parameter study

Specification

Alias: none

Argument(s): INTEGER

Description

num_steps defines the number of steps that are taken in the direction of the vector. The magnitude of each step is determined in conjuction with the rest of the method specification.

Default Behavior

The user is required to specify num_steps for a vector parameter study. There is no default value.

This study performs function evaluations at both ends, making the total number of evaluations equal to num_steps+1.

Usage Tips

The study has stringent requirements on performing appropriate steps with any discrete range and discrete set variables. A num_steps specification must result in discrete range and set index steps that are integers: no remainder is currently permitted in the integer step calculation and no rounding to integer steps will occur.

Examples

    num_steps = 10
