[ADMB Users] Missing overloaded operators (+=, -=) in random effects

[dave fournier]

Easiest thing is to find a similar function such as


df1b2vector& df1b2vector::operator -= (const df1b2vector& _x)
{
   ADUNCONST(df1b2vector,x)
   check_shape(*this,x,"operator -");

   int mmin=x.indexmin();
   int mmax=x.indexmax();

   for (int i=mmin;i<=mmax;i++)
   {
     (*this)(i)-=x(i);
   }
   return *this;
}

and change it to

df1b2vector& df1b2vector::operator -= (const dvector& _x)
{
   ADUNCONST(dvector,x)
   check_shape(*this,x,"operator -");

   int mmin=x.indexmin();
   int mmax=x.indexmax();

   for (int i=mmin;i<=mmax;i++)
   {
     (*this)(i)-=x(i);
   }
   return *this;
}

Note that this is a class member function for df1b2vector
so you need to put it in the class declaration header file as

df1b2vector& operator -= (const dvector& _x);
