How should the step parameter be set in Matlab?

In MATLAB, the step function is used to plot the response of a unit step signal. The syntax of the step function is:

step(sys)

The sys is the transfer function or state-space model of the system. The step function has many optional parameters that can be used to set the style of the plot, such as line color, line style, markers, etc. Some commonly used parameters include:

1. ‘r’: Set the color of the line to red.
2. ‘b’：Set the line color to blue.
3. Set the line color to green.
4. ‘–’: Set the line to be dashed.
5. “Set the line style to dashed.”
6. ‘Set the width of the line’
7. “Marker: set marker type”

For example, you can use the following code to set the line color of the plot to red, line style to dash, and line width to 2:

step(sys,'r--','LineWidth',2)
