Hi all,

I am plotting some data from a power-inverse law and using the following:

loglog(E2dist,E2PrdB,'+g'), hold on

p = polyfit(log(E2dist),log(E2PrdB),1);

m = p(1);

b = exp(p(2));

%mean=mu(1);

%std=mu(2);

loglog(E2dist, b.*E2dist.^m,'-m*');

This works fine. But when I change to

[p,S,mu] = polyfit(log(E2dist),log(E2PrdB),1);

my straight line fit is separated vertically from my original data points?

Hope you can help.

cheers
