Normalize data set

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?
