Errors for the slope and intercept

How can I get the uncertainty for the slope and intercept when using this code
Const = polyfit(log10(x),log10(y), 1);
m = Const(1);
k = Const(2);
b_fit = (10^k) * (x.^m4);

use the two output form of polyfit and the two output form of polyval

okay so when you call polyval pass in log10 of the x locations and the second output will reflect that log space .
