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.
variables
continuous_design 1
initial_point 1.0

# Add 2.0 to x1 and increment s1 by 1 element in each step
