The picture explains everything.
Only V varies from 0 to 450.
Rest variables such as (rho), S, W are constant (those can be replaced with numbers in MATLAB).

So how do i plot such a graph?
oh forgot to mention the axes.
The y axis should "Tr" and x - axis should be "V".

Well, plug all the constant terms in the equation of Tr and leave v as an independent variable, it just seems to be ordinary algebra.

Do you know how "for" loops work?

hmmm...
i recently learned for loops in C++...
i never knew if they existed in matlab....
