ETL (Expressions Template Library) is a header-only library for C++ providing vector and matrix classes with support for Expression Templates to perform very efficient operations on them.
The library supports numerous features:
- Matrix and vector (runtime-sized and compile-time-sized)
- Simple element-wise operations
- Reductions (sum, mean, max, ...)
- Unary operations (sigmoid, log, exp, abs, ...)
- Matrix multiplication
- Convolution (1D and 2D and higher variations)
- Max Pooling
- Fast Fourrier Transform
- Symmetric matrix adapter (experimental)
- Sparse matrix (experimental)
If you are new to this project, I recommend reading Getting Started.
