step_vector
Size of step for each variable
Specification
Alias: None
Arguments: REALLIST
Description
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.
Examples
variables
continuous_design 1
initial_point 1.0
descriptors 'x1'
discrete_design_set
string 1
elements 'bar' 'baz' 'foo' 'fuzz'
initial_point 'bar'
descriptors 's1'
method
vector_parameter_study
num_steps = 3
# Add 2.0 to x1 and increment s1 by 1 element in each step
step_vector = 2.0 1
