Plotting Pacejka Tire Model in MATLAB

Hello!

I am developing my own car model in MATLAB/Simulink, and today, I have written the Pacejka's equations into my .m file. Right after finishing that, I have tried to make some plots, so that I could take a look at the tire's characteristics and verify whether or not my model works, but I'm a bit of a newbie with MATLAB environment, and the documentation only explained how to plot very trivial functions, as a sine function. Needless to say, a Pacejka's model is a much more complex model, and I felt really lost with how to solve this problem, so I was hoping some of you could lend me a hand. It would be much appreciated.

Thank you. Vicente.
