indexing through nlinfit in a seperate script only returns one fitted set of values
0
I am trying to pass three cell2mat arrays for I,V,H through this function and plot the result of the parameter from the nlinfit model below. But when the code is run it plots nothing and only stores one value. Any help is appreciated:)
function [Icp] = Fraunhofer_Function(I,V,H)
V1 = @(b,I)(b(1).*sign(I).*real(sqrt(I.^2 - (sign(I).*( (b(2)+b(3)/2) )).^2)) + b(4));
Vthresx = find(V<=1e-3 & V>=0);
Ithresvec = max(I(Vthresx));
Voffsetx = find(I<=0.1e-3 & I>=-.1e-3);
Voffset = max(V(Voffsetx));
Rn = (max(V)-min(V))/(max(I)-min(I));
beta1 = [Rn; Ithresvec; -Ithresvec; Voffset]; %Init values b1=Rn b2 = Icp, b3 = Icm, b4 = Voffset
opts = statset('MaxIter', 500000, 'MaxFunEvals', 100000, 'RobustWgtFun', 'andrews');
B1 = nlinfit(I, V, V1, beta1, opts ); %Fit
Icp = V1(B1,V);
end
files = dir('*.xlsx*');
for k =1:length(files)
filenames = files(k).name;
txt = 'I,V,H';
[num,txt,raw] = xlsread(filenames);
%Put data into numerical columns
Idata = num(:,1)'; Vdata = num(:,2)'; Hdata = num(:,3)';
[Hu,~,idx] = unique(Hdata);
Isplit = splitapply(@(x) {x}, [Idata(:)],idx);
Vsplit = splitapply(@(x) {x}, [Vdata(:)],idx);
Hsplit = splitapply(@(x) {x}, [Hdata(:)],idx);
for l = 1:length(Isplit)
I = (Isplit{l,1});
V = (Vsplit{l,1});
H = (Hsplit{l,1});
%fit the data to the functional form
Icp = Fraunhofer_Function(I,V,H);
end
end
