What is a step response in MATLAB?
Step Response Plots
step( sys ) plots the response of a dynamic system model to a step input of unit amplitude. The model sys can be continuous- or discrete-time, and SISO or MIMO. For MIMO systems, the plot displays the step responses for each I/O channel.
Is there a step function in MATLAB?
The step function is one of most useful functions in MATLAB for control design. Given a system representation, the response to a step input can be immediately plotted, without need to actually solve for the time response analytically.
