Description

In spite of the fact that some packages (even in Mathematica) for computing the integer Smith Normal Form of a matrix over the integers are already available, some of them (e.g. the one from D. Jabon) eventually fail to give the diagonal matrix properly sorted. This notebook provides an alternate method for computing the Smith Normal Form for matrix over the integers. Notice that the point of this notebook is correctness better than efficiency, so that previous algorithms will eventually run faster than ours.
