I have a main class which takes 2 arguments, Two arguments(Same) are coming from 2 another classes which are doing differnet computations . Now I need to define a 3rd argument which allows user to specify which class he wish to chooses .
Lest say : Main Class is : obj = mainClass (a,b) other 2 classes which uses a,b are : 1) obj = Sum(a,b) 2) obj = Diff(a,...

I want to see the plot for absolute value of FPhi(abs(Fphi)) in real frequency grid and not with this fftshift. What should i do to see the real plot and not the centered/fftshift one. P.s I tried removing the fftshift commands but didn't work.
mesh(fftshift(fx),fftshift(fy),fftshift(abs(FPhi(:,:,ik))),'FaceColor','flat'); view(0,90);
