Index exceeds matrix dimensions. Error

I get the error " Index exceeds matrix dimensions " when I test the function CharactOne bellow. However, I tested individually the second, forth and sixth line of code and they give good results. I don't understand what is the problem with the code, I am guessing it has to do with the if statement , but can't spot the mistake.

function CharactOne= CharactOne(baseType,TCType,u,T,paramsBase,paramsTC)

lambda=-1i*CharactExpLib(baseType,u,paramsBase)-u*CharactExpLib(baseType,-1i,paramsBase);

if strcmp(TCType,'G')|| strcmp(TCType,'IG')

      CharactOne=CharactFunSLib(TCType,lambda,T,paramsTC);
  else
       CharactOne=CharactFunALib(TCType,lambda,T,paramsTC);
  end

end

Doesn't the error message include information as to which line caused the error?

Please paste in ALL the red error text, ALL of it.

It doesn't. This is the message :

>> CharactOne(baseType,TCType,u,T,paramsBase,paramsTC)
Index exceeds matrix dimensions.

This is one of the many reasons I very rarely write a function nowadays without using validateattributes on every one of my input arguments. It takes very little time and cuts out so many silly errors later in the code.

You must have a variable called CharacterFactoryOne in your workspace.

newname = CharacterFactoryOne;
clear CharacterFactoryOne

Genius! thanks alot. Correct me if I'm wrong ... I had a variable with that name and because of its definition the result didn't 'fit' in the cell...is that a good description of the problem?

[Guillaume]

Matlab was trying to access the element of the matrix CharacterFactoryOne at row baseType, column TCType, page u, etc., and that matrix didn't have that many element (and probably that many dimensions).

But CharacterFactoryOne was not in the original code that was posted. I thought the problem was that the return argument was the same name as the function name itself (CharactOne).
