The LLL parameter α = m1/n1 has to satisfy 1/4 < α ≤ 1, but here the default value is 1.
See pages 6-9 of slides and pages 406-416, An Introduction to Mathematical Cryptography, J. Hoffstein, J. Pipher, J.H. Silverman, Undergraduate Text, Springer, August 2008.
The matrix can be entered either (i) as a string of mn integers separated by spaces, or
(ii) cut and pasted from a text file, with entries separated by spaces and each row ended by a newline.
If the matrix entered has LD rows, this is detected during the initial Gram-Schmidt process when Di becomes 0.
