DESCRIPTIONThe software package 4ti2 is a suite of command-line tools for addressing algebraic, geometric and combinatorial problems on linear spaces.
DATA STRUCTUREThe main concept of 4ti2 remains the same: a project is defined via a file foo[.mat] containing the problem matrix. Related sets such as Graver basis or Markov basis are put into foo.gra and foo.mar, respectively.
Input files and output files usually contain a matrix or a list of vectors (written as a matrix) in a standard encoding such as
2 4 1 1 1 1 1 2 3 4
There are only few exceptions, for example in a file foo.vars containing user specified variable names:
3 a b x
