[Boost-users] Question regarding ublas::identity_matrix

Hi all,
I'm a newcomer to uBlas.
Please consider the following code:

identity_matrix<double> matI(3);
int row = matI.size1();
int col = matI.size2();

now that matI has the same number of rows and columns, why the 
identity_matrix template class has two "size" member functions: size1() and 
size2()? And has two "size" member variables: size1_ and size2_? Why not use 
just size() and size_?
