Hi

Can ae_vector be used together with std algorithms? How is the correct way to do it:

alglib::real_1d_vector a;
a.setlength(100);
std::fill((double*)a.c_ptr(),(double*)a.c_ptr() + a.length(),0.0);

Thanks,

With ae_vector you can just take pointer to the first element of the array - elements are stored contiguously, such order is 100% compatible with STL. With ae_matrix, however, you should be very careful - elements are stored row-by-row, with additional padding between rows, which should be taken into account (this padding is used to align data in memory).
