Hi
I want to ameliorate the smooth of attached curve.
rload=[100;1e3;10e3;100e3;1e6;10e6];
power_hs=[1.570642571; 15.23486212; 1.12E+02; 1.37E+02; 81.69126068; 10.5949686];
loglog(rload,power_hs,'m')

% Your data:
rload=[100;1e3;10e3;100e3;1e6;10e6];
power_hs=[1.570642571; 15.23486212; 1.12E+02; 1.37E+02; 81.69126068; 10.5949686];
loglog(rload,power_hs,'mo')
%
% Interpolate in log space:
powi = 10.^(interp1(2:7,log10(power_hs),linspace(2,7,1000),'spline'));
%
% Plot interpolated curve
hold on
loglog(logspace(2,7,1000),powi,'m-')

Like I said in your duplicate question you can use interp1(), conv(), sgolayfilt(), or splines to interpolate in and smooth the points. That's what Chad did, and the result looks pretty good to me. You can adjust the parameters to adjust the smoothness if you want.
