In this plot I want to insert the mean, the variance and standard deviation of this signal. Is there a particular function or a toolbox that executes it?

If you signal data is in vector y, say, then

ymean = mean(y);
ystddev = std(y);
yhi = ymean+ystdev;
ylo = ymean-ystdev;
xrange = [0 60]; % or whatever you want
plot(xrange, [ymean ymean],xrange,[ylo ylo], xrange, [yhi yhi])
