  • Ticket #12051 – Description

    initial v13  
    1 Matrices over {{{QQ}}} or {{{RR}}} do not have an method {{{LLL(...)}}} like matrices over {{{ZZ}}}.
     1Matrices over `QQ` do not have a method `LLL(...)` like matrices over `ZZ`. Here is a simple implementation:
     2
     3 1. get rid of the denominator
     4 2. call the {{{LLL}}} method of integer matrices
     5 3. set the denominator back.
     6
     7Note: in previous version it was suggested that such an approach might be useful for matrices over `RR`. But it is not completely clear how to do that efficiently.
