ginv implements the involutive basis algorithm by V. P. Gerdt and Y. A. Blinkov in C++. For a list of the main features, please see below.
Moreover, the implemented computational methods are made accessible by ginv to a higher level programming language as a Python module.
ginv is designed so as to be able to deal with polynomial systems, systems of differential equations, and finite difference schemes in the future.
Some features of ginv (see Publications for more information):

Installing ginv



To install the GINV software under Unix one needs the library gmp ( assembled with C++ support. For the code optimization under a given computer architecture one can properly adjust the C++ compiler options in the file

The assemblage of the module ginv is done in line with the standard scheme for Python:

    python build
For installation into the standard folder (and assemblage if the module has not been assembled):
    python install
For installation into a non-standard folder:
    python install --prefix=/home/user/pyginv


Installation under Windows uses the pre-compiled module ginv. This imposes some restrictions on the type and capacity of a processor. The module ginv is built-up with i586 code. This may lead to a substantial slow-down in performance, for instance, when a 64-bit processor is used.

Assemblage under Windows is similar to that under Unix.
