Welcome To MatX’s Documentation!#
MatX is a modern C++ library for numerical computing on NVIDIA GPUs and limited support for CPUs. The main features include:
Compile-time expression evaluation for generating GPU kernels
Near-native performance for GPU kernels while using a syntax similar to Python or MATLAB
Easy frontend API to many popular CUDA libraries
Header-only without need for compilation
Single data type used across entire API
Intuitive error messages
To start building tests, examples, and benchmarks, visit the Build Integration guide. This page also lists the requirements for each type of build.
If you’re new to MatX and want to jump right in, we recommend starting with the Quick Start guide. This guide walks through the MatX concepts and primary API functions to give you the tools to make your first application using MatX.
If you prefer learning by looking directly at complete examples, take a look in the examples directory. Some
examples have full walk-throughs in the Example Applications section of the documentation.
Lastly, an API Reference guide is available for every function in MatX.
Note
We strive to make sure that every function in the MatX API has at least one example and one unit test. All example code in the API section is cross-referenced from the unit tests. This means that the examples in this documentation should always be correct and unit tests would catch any errors before they’re introduced or modified in the docs.
