I have two vectors.I need to make the smooth plots.But I am getting straight lines which are not appealing.Kindly suggest me any way of having smooth plots.
I have following data
x=[0 0.025 0.05 0.075 0.1 0.125 0.15 0.175 0.2 0.225 0.25 0.275 0.3 0.325 0.35 0.375 0.4 0.425 0.45 0.475 0.5 0.525 0.55 0.575 0.6 0.625 0.65 0.675 0.7 0.725 0.75 0.775 0.8 0.825 0.85 0.875 0.9 0.925 0.95 0.975 1 ] ;
y=[1.422 1.427 1.431 1.396 1.396 1.377 1.377 1.358 1.357 1.338 1.338 1.319 1.318 1.301 1.301 1.288 1.287 1.278 1.278 1.274 1.274 1.275 1.276 1.282 1.282 1.294 1.294 1.309 1.310 1.328 1.328 1.348 1.348 1.367 1.367 1.386 1.386 1.413 1.413 1.039 1.025] ;
plot(x,y,'r')
Thank You

sp = spline(x, [0 y 0]);
xq = linspace(min(x), max(x), 25);
yq = ppval(sp, xq);
plot(x, y, 'g', xq, yq, 'r')
If you increase the 25 to make the curve more accurate then although it will be smoother than the raw data, it will still show a lot of bumps.
