What is this error I get?

Hi

I am using an evolution Local Gaussian Distribution active contour for automated segmentation and I get this error:

Subscript indices must either be real positive integers or logicals.
Error in evolution_LGD>NeumannBound (line 56)
g([1 nrow],[1 ncol]) = g([3 nrow-2],[3 ncol-2]);
Error in evolution_LGD (line 19)
u=NeumannBound(u);
Error in ruller>LGD (line 234)
    phi =evolution_LGD(Img,phi,epsilon,Ksigma,KONE,KI,KI2,mu,nu,lambda1,lambda2,timestep,alf);
Error in ruller (line 124)
      LGD() 
>> 

Can someone explain me please, what this error means? What is the wrong?

Thank you

do you mean to do

g(1:nrow,1:ncol) = g(3:nrow-2,3:ncol-2);

I don't think it is that error, since, it is already there from the original function. And I know that it works.

The problem must lie where the ruller.m is since this is my code I am trying to develop.

I still cannot understand the root of the trouble
