Hi Matthias, Yes, I agree that's an important generalization. On Jul 6, 2004, at 4:54 AM, Matthias Troyer wrote:
You however point out an important requirement for generic algorithms on vector spaces: they should not require that a vector can be accessed with operator[] and a single subscript, or that once can construct a vector by passing just the size to the constructor. These too narrow requirements of the Iterative Template Library ITL, caused us to introduce the "vector space" concept in the our Iterative Eigenvalue Template Library IETL.
