I have the following code in two separate .m file in the same folder running on Matlab 2015a:
function Test
I=[1 2 3 5; 2.1 2.9 3 4; 3 3 4.1 4; 5 3.5 5.2 6];
P=[1 2 3 4; 2 3 4 5; 4 5 6 7; 5 6 7 8];
x0=[2, 3]
x = lsqcurvefit(modelP,x0,I,P)
end
function [h]=modelP(x,I)
h=x(1)*I+x(2)*1.5
end
Running test it gives me the following error:
Error using modelP (line 2)
Not enough input arguments.
Error in Test (line 5)
x = lsqcurvefit(modelP,x0,I,P)
I cannot figure out why. Can someone help me, please?

I solved it calling the function as:
lsqcurvefit(@(x0, I) modelP(x0, I),x0,I,P)
This is not very clear in the documentation. Thanks anyway.
