I'm having the same issue. I would like to smooth my plot that's on a log scale using semilogx. I have tried both smoothingspline and interpl and neither hold. Please provide examples of code using semilogx because the examples from matlab are using linear aplots nd those don't transfer :)
My normal plot:
f1 = figure;
w = [10^2,10^3,10^4,10^5,10^6];
Vc2 = [5,5,4.45,1.055,0.114];
semilogx(w,Vc2);
xlabel('\omega','FontSize',20,'FonWhentWeight','bold')
ylabel('|V_C(t)|','FontWeight','bold')
title('Part 2 Capacitor')
My attempt at interpl:
f1 = figure;
w = [10^2,10^3,10^4,10^5,10^6];
Vc2 = [5,5,4.45,1.055,0.114];
%Smooth the curve:
wi = logspace(2,6,150);
vi = interp1(w, Vc2, wi, 'spline');
semilogx(w,Vc2,'o',wi,vi);
xlabel('\omega','FontSize',20,'FonWhentWeight','bold')
ylabel('|V_C(t)|','FontWeight','bold')
title('Part 2 Capacitor')
it's somewhat doing it but I would like something much closer to the original shape of my first plot.
