Matlab classes in a array

I've a issue with matlab constructors when I try to instantiate an array of classes.

I get the following error:

??? The following error occurred converting from volta to double:
Error using ==> double
Conversion to double from volta is not possible.

Error in ==> circuito>circuito.iniciarNovaVolta at 37
            Circuito.Voltas(Circuito.Nvoltas) = Volta(Nmaxpiloto);

Error in ==> testes at 99
c1.iniciarNovaVolta(10);

And my code is:

function iniciarNovaVolta(Circuito, Nmaxpiloto)
            Circuito.Voltas(Circuito.Nvoltas) = Volta(Nmaxpiloto);
            Circuito.Nvoltas = Circuito.Nvoltas + 1;
end

The contructor at Volta class is: 

function Volta=volta(Nmaxpiloto)            
    if(nargin>0)    
        %Volta.Melhortempovolta=Melhortempovolta;  
              Volta.Nmaxpiloto=Nmaxpiloto;                               
           end        
end

I had this issue more than once, but the types looks right. Could you tell me what I can't see ? 

function Volta=volta(Nmaxpiloto) 
if(nargin>0)

Check your types. I'm guessing that Volta(Nmaxpiloto) is of type double and Circuito.Voltas(Circuito.Nvoltas) is of type volta. This can't be done. Sounds like you are mixing a lot of OOP with MATLAB, which is not to say that you can't. You might want to look at this link: http://www.mathworks.com/help/techdoc/matlab_prog/f2-47534.html#bqt_gwr to see the valid MATLAB classes.
