Вычисление унимодулярных матриц

Abstract

Here we give an algorithm for solving the following problem. Let m<n integer vectors be given in the n-dimensional real space. Their linear span forms a linear subspace L in R<sup>n</sup>. It is required to calculate such an unimodular matrix that a linear transformation with it transforms the subspace L into a coordinate one. Also, programs that implement the algorithms and power transformations, for which they are needed, are given.
