As far as I know, there is nothing special about themplate 
classes with regards to operator overloading, so you can follow 
the examples in there: http://dlang.org/operatoroverloading.html

which in your example would yield:

Matrix opOpAssign(string op)( Matrix rhs )
{	
   for( size_t i =0 ; i < M ; ++i )
   {
     for( size_t j =0 ; j < N ; ++j )
     {
       mixin("array_[i*N+j]" ~ op ~ " rhs.array_[i*N+j] ;") ;
     }
   }
}

Bonus! all ...= operators implemented at once!
