# YATeTo

It is **Y**et **A**nother **Te**nsor **To**olbox for discontinuous Galerkin methods and other 

applications. You can find much more information about the package 

[here](https://arxiv.org/abs/1903.11521).

## Installation

```bash

pip install -e .

```

## Usage

```python

from yateto import *

...

def add(g):

  N = 8

  A = Tensor('A', (N, N))

  B = Tensor('B', (N, N, N))

  w = Tensor('w', (N,))

  C = Tensor('C', (N, N))

  

  kernel = C['ij'] <= 2.0 * C['ij'] + A['lj'] * B['ikl'] * w['k']

  g.add(name='kernel', ast=kernel)

# 'd' - double precision; 'hsw' - haswell-like architecture

arch = useArchitectureIdentifiedBy("dhsw")

generator = Generator(arch)

add(generator)

generator.generate(output_dir, GeneratorCollection([LIBXSMM(arch), Eigen(arch)]))

...

```
