Hi all !! First of all, thank you to all contributors of Scilab. However, I have a problem to calculate the estimated error on each parameter calculated with leastsq.
For example if I have the simple following function to fit: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! function y = fun2fit(x, c) y = c(1)*x*x + c(2)*x + c(3); endfunction function e = myerror(c, x, y) e = fun2fit(x, c) - y; endfunction // Data x = [ 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6]'; y = [5.02 6.08 3.33 -0.93 -0.22 7.83 16.52 15.55 2.67 -11.42 -11.78 5.09 25.25]'; // First guess c0 = [1 1 1]'; y0 = fun2fit(x, c0); // least square [f, copt] = leastsq(list(myerror, x, y), c0) !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I'd like to have an estimated error on each of the 3 element of copt. Any idea ? Thanks !
