D.8.7.17 realLLL
Procedure from libraryrecover.lib (see recover_lib).
- Usage:
- realLLL(M); matrix M
- Assume:
- The columns of M represent a basis of a lattice.
The groundfield is the field of real number or the field of complex numbers, the elements of M are real numbers. - Return:
- matrix: the columns representing an LLL-reduced basis of the lattice given by M
