I need to make two plots of volume as a function of time vs pressure as a function of time. When plotted the graph will have an enclosed area. I am having trouble on how to have matlab plot these two functions against each other.
My experience with matlab is having a function defined in a script file. I have not been exposed to using a function m file to define a function and reference it in a script. My functions are as follows where (t) is the only variable, everything else is defined earlier in the file. I need to graph P vs Vc and P vs Ve. The order of magnitudes of Vc and Ve is different by 10^3 hopefully that won't matter. Vc =@(t) vc*sin(omega*t); Ve =@(t) ve*cos(omega*t); A =@(t) Vc(t)/(R*Tc) + vtl/(R*Ttl) + vr/(R*Tr) + Ve(t)/(R*Te); P =@(t) M/A(t);
