i have my problem to work with functions. do not get any results from it. I know that it work, so the problem is just by my execution of the function.
How can i avoid following error?
>> ref_model(1,2)
Index exceeds the number of array elements (2).
Error in ref_model (line 7)
I=p(2)./(d(:,1)+p(1))+p(3)./(d(:,1)+p(1)).^2+p(4)./(d(:,1)+p(1)).^4;
>> myQ(1)
Index in position 2 exceeds array bounds.
Error in myQ (line 5)
Q=sum(r(:,1).*(ref_model(x,r(:,1))-r(:,2)).^2);

From the function r should be a m*2 matrix. It should have two columns. And x should be a 1*4 array.

thanks for your support but i do not work:
>> x=[1 2 3 4]; myQ(x)
Index in position 2 exceeds array bounds.
Error in myQ (line 5)
Q=sum(r(:,1).*(ref_model(x,r(:,1))-r(:,2)).^2);

r = rand(10,2) ;
global r ;
x = 1:4 ;
Q = myQ(x) ;
Try avoiding gloabl, instead you can make it as a input to function.
