fast Legendre transform
This is a minimal Python package for fast discrete Legendre transforms (DLTs). The implementation uses a recursive version of the matrix relations by Alpert & Rokhlin (1991) to compute the DLT via a discrete cosine transform (DCT).
The package can be installed using pip:
pip install flt
For more information, please see the documentation.
Current functionality covers the absolutely minimal use case. Please open an issue on GitHub if you would like to see anything added.
