Hi
I have a data set giving me (time, voltage), and I wish to normalize the data set. Is there a smart way to do this in MatLAB?
Also, is there a way to integrate such a data set?
Best wishes amd thanks for any help, Niles.

v = rand(1,100); %invent data
t = linspace(1,10,100);
vn = v./max(v); %normalize
integral = trapz(t,vn);

Depends on how you define integrate. Maybe you want sum(data(:)), then to normalize
normalizedData = data ./ sum(data(:));
Or you can divide by the max of the data instead of the sum of it all, depending on how you define normalize. There are different definitions you know. What's yours?
