How to plot ramp function in time domain

How Can I plot Ramp function in time domain? I tried it using superposition by creating a line and then creating another line which is shifted and then I added them together but still it is not working!

Please post your code.

Tell us:

• What you want it to do,
• What it currently does that you do not want it to do,
• what it is currently not doing that you want it to do,
• any errors it throws

If this is in the context of the Control Systems Toolbox, Signal Processing Toolbox, and some others, the coding would be different that it would be if you were building it yourself in core MATLAB.

Here is an example of plotting the unit ramp function :

You could extend the above concept to plot the required ramp function.

Additionally, if you are looking to plot a time response, the lsim function could be useful :
