Re: Plots points smoothing

A simple solution is to try a running mean over N points (N must be an even number in this example):

N = 10;
f = repmat (1/N,1,N);
a2 = conv (a,f); a2 = a2(N/2:end-N/2);
plot(a,'b'); hold on
plot(a2,'r'); hold off

Hi all,

I want to customize a graph with two options. The first one is to smooth lines that union the diferent time points.

The second, if it is posible is to envelope, and connect the maximum points with the minimum smothing this union.

If you run this file you will see "peaks" I want to elimite them and make more homogeneus graphic.
