Inside a 2 stroke engine, I have a set of data of crank angle and pressure, which is huge (500). And I need to find the volume of the cylinder,

I know the value of Vd, theta, r and R.

I already import the data into Matlab.

My problem is how can I write the matlab code so that I can get the plot of Pressure and theta?

Is the data that you show the pressure and theta values?

Side note: I suggest that you give your filenames more descriptive titles than "equation", "exercise", and "E".

Yes, the left side is the theta, and the right column is the pressure.

plot(Data(:,1), Data(:,2))

THank you.

But how to show on the title on the axis?

I assume you want to add a title to the plot? After using the plot line, type

title('What you want the title to be')
