Hello, I would like to speed up this code, any sugestions
Rm, Zm and Cm are 1700x1700
f = linspace(1e3,5e6,750); % Hier gibt man den Frequenzbereich an
w = 2*pi*f';
parfor k=1:length(f)
Zm = Rm+w(k)*1i*Lm;
Gama = Kk*(Zm\Kkt);
YYn = w(k)*1i*Cm + Gama;
Zn = inv(YYn);
Amp(k) = abs(1-Zn(jj,1)/Zn(1,1));
end
I do not have a GPU

Sorry, nothing occurs to me. You take the trouble to invert YYn but then only use a single row of it, so maybe you could focus on that piece of algebra.
