  This looks like a good approach. My problem with the operators is the  
fact that there are are many types present, with more operators, like:

- scalars (double)
- vector
- matrix

  For example, "a*b" could mean multiplication of:
- a vector with a scalar
- a vector with a matrix
- a matrix with another matrix

  Similar for the others, so reading code wich uses operators kinda sucks...
