# teneva


## Description

This python package, named **teneva** (**ten**sor **eva**luation), provides a very compact implementation of basic operations in the tensor-train (TT) format, including TT-SVD, TT-ALS, TT-ANOVA, TT-cross, TT-truncate, "add", "mul", "norm", "mean", etc. The program code is organized within a functional paradigm and it is very easy to learn and use.


## Installation

The package can be installed via pip: `pip install teneva` (it requires the [Python](https://www.python.org) programming language of the version >= 3.6). It can be also downloaded from the repository [teneva](https://github.com/AndreiChertkov/teneva) and installed by `python setup.py install` command from the root folder of the project.

> Required python packages [numpy](https://numpy.org), [scipy](https://www.scipy.org) and [numba](https://github.com/numba/numba) will be automatically installed during the installation of the main software product.


## Documentation and examples

- See detailed [online documentation](https://teneva.readthedocs.io) for a description of each function and numerical examples.
- See the jupyter notebook `./demo.ipynb` with brief description and demonstration of the capabilities of each function from the `teneva` package, including the basic examples of using the TT-ALS, TT-ANOVA and TT-cross for multidimensional function approximation.
