Program Isometry
Usage
Isometry 'file1' 'file2 [-d=n] [-s=n] [-b] [-b=n] [-B=n] [-g] [-v] [-p]
file1: matrix_TYP containing a set of m NxN-matrices, the first of which,
must be symmetric and positive definite.
file2: matrix_TYP containing a set of m NxN-matrices, the first of which,
must be symmetric and positive definite.
Description
Computes a single g in GLn(Z) with the property gTr *
Fi1 * g = Fi2 for all Fi1 in
'file1' and Fi2 in 'file2'.
Options
-d=n : Depth up to which scalar products are calculated. The value
should be small.
-s=n : The n-point stabilizer with respect to different basis will be
calculated.
-b=n : Use Bacher polynomials up to deepth n.
-B=n : Use Bacher polynomials with vectors having scalar product n
-v,-g : Read additional data from 'file'. If -v is given the program
assumes that the short vectors of the first form in 'file'
are given below the forms.
If -g is given, the program assumes known generators for
the automorphism group to be given below any other information in
'file'.
-p : Write additional output to the file ISOM.tmp
