Size of step for each variable
Alias: none
Argument(s): REALLIST
The step_vector
keyword specifies how much each variable will be incremented in a single step.
step_vector
works in conjunction with num_steps
, which determines the number of steps taken during the vector_parameter_study
. If instead of step_vector
, final_point
is specified with num_steps
, Dakota will infer the step sizes.
Entries in the step_vector
are the actual amounts by which continuous and range variables are incremented. For set variables, step_vector
entries are interpreted as indexes into the underlying set.
Default Behavior
The user is required to specify either final_point
or step_vector
. There is no default definition for the vector.
