# Data Transfer Tools for C++ Linear Algebra Libraries.
DTT is a **header-only** library that provides data transfer tools between C++ linear algebra libraries.
Currently, it supports data transfer between the following libraries:
* Eigen (>=3.3.x)
* Armadillo (>=9.x)
* OpenCV (cv::Mat) (2.x, 3.x, 4.x) 
* ArrayFire (>=3.x)
* LibTorch (PyTorch C++) (>=1.x)

Tested on:
* MacBook Pro (13-inch, 2017)
* Mac OS X Mojave (10.14.5), Clang 10 (clang-1000.11.45.5), Xcode 10.1 with the following libraries:
* * OpenCV 4.1.1 (stable, built from source)
* * Eigen 3.3.7 (stable)
* * Armadillo 9.600.5 (stable)
* * ArrayFire 3.6.4 (stable)
* * LibTorch (1.3.0.dev20190820)

Install dependencies:
```
brew install eigen
brew install armadillo
