Hi, I would like to force a slope value and know the intercept for that particular slope value....
Const = polyfit(log10(x),log10(y), 1);
m = Const(1);
k = Const(2);
b_fit = (10^k) * (x.^m);
This is the one that I use to return both... I want to force m and return k

m = WhatYouWantItToBe
k = mean(log10(y)-m*log10(x))
