I tried the code and got these compilation errors.
sorry... iterator2 has to be initialised from "standard" begin() and end() of
iterator1:
typedef matrix<double> MatType;
MatType m(3,3);
for(MatType::iterator1 i1 = m.begin1(); i1!=m.end1(); ++i1) 
    for(MatType::iterator2 i2 = i1.begin(); i2!=i1.end(); ++i2)
        *i2 = 2;
this time I tested the code (g++ v. 4.02, boost 1.33.1).
Hope that helps,
Alexander.
Thanks. Unfortunately, it doesn't compile for me on Visual Studio.
(VS 7.1, boost 1.33.1)
