IntegerMatrix

✓ from fpylll import IntegerMatrix

✗ from fpylll import IntegerMatrix

Create an integer matrix and run LLL reduction.

from fpylll import IntegerMatrix, LLL A = IntegerMatrix.from_matrix([[1,2,3],[4,5,6],[7,8,10]]) B, _ = LLL.reduction(A) print(B)

Debug

Known issues

breakingIn version 0.6.0, the import path for core classes changed. Previously 'from fpylll.fplll.gso import GSO' now must be 'from fpylll import GSO'.

fix

Use top-level imports: from fpylll import IntegerMatrix, LLL, GSO, BKZ

affects: >=0.6.0

deprecatedThe function 'fpylll.fplll.gso.MatGSO' is deprecated; use 'fpylll.GSO.Mat' instead.

fix

Replace MatGSO with GSO.Mat

affects: >=0.5.0

gotchaIntegerMatrix uses 0-based indexing, but many lattice examples in papers use 1-based. Off-by-one errors are common when porting code.

fix

Verify matrix dimensions: rows = number of basis vectors, columns = dimension.

affects: all

gotchaLLL.reduction returns a tuple (reduced_matrix, transformation_matrix). Forgetting to unpack the tuple leads to TypeError.

fix

Always use: B, T = LLL.reduction(A)

affects: all
