How does normr work?

Yes i realize it returns a matrix with the values having a norm of 1 but how exactly does it do this? My knowledge of statistics is sorely lacking.

Thanks!

You can open the m-file (type norm.m) and find something like this:

[mr,mc]=size(m);
if (mc == 1)
  n = m ./ abs(m);
else
  n=sqrt(ones./(sum((m.*m)')))'*ones(1,mc).*m;
end

That's all ...
