stepDataOptions

Options for the step command

Syntax

opt = stepDataOptions

opt = stepDataOptions(Name,Value)

Description

opt = stepDataOptions creates the default options for step.

opt = stepDataOptions(Name,Value) creates an options set with the options specified by one or more Name,Value pair arguments.

Examples

Specify Input Offset and Step Amplitude Level for Step Response

Create a transfer function model.

sys = tf(1,[1,1]);

Create an option set for step to specify input offset and step amplitude level.

opt = stepDataOptions('InputOffset',-1,'StepAmplitude',2);

Calculate the step response using the specified options.

[y,t] = step(sys,opt);

Input Arguments

Name-Value Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: ...,'InputOffset',2

InputOffset — Input signal offset level

0 (default) | scalar

Input signal offset level, specified as the comma-separated pair consisting of 'InputOffset' and a scalar, for all time t < 0, as shown in the following figure.

StepAmplitude — Change of input signal offset

1 (default) | scalar

Change of input signal offset level, specified as the comma-separated pair consisting of 'StepAmplitude' and a scalar, which occurs at time t = 0, as shown in the previous figure.

Output Arguments

opt — Options for the step command

step options set

Options for the step command, returned as a step options set.
