Hello, i am doing some schmidt-analysis on a stirling engine, but my question is rather simple. I have the measured presure P at a given time T as a 229x2 matrix, i also have a function, V__total(T), for the total volume of the engine at a given time T.
I then go on to create a pointplot PV, which is rougly the shape of a potato. I now want to find the area enclosed by this point plot, is there any way?
I do something like:
> DATA:=ImportMatrix(filepath,skiplines=1); %import data from .txt file, skip header line.
>P:=DeleteColumn(DATA,1); %Isolate presure column
>T:=DeleteColumn(DATA,2); %Isolate time coliumn
>V:=V__total~(T); %Generate volume vector as a function of time T
Is there any wat to finde the area enclosed by the curve/
