The FLAGLET code provides high-performance routines for fast wavelet analysis of signals on the ball using the Flaglet transform (ArXiv | DOI). It exploits S2LET, FLAG and SSHT codes. The flaglet transform is theoretically exact, i.e. the original signal can be synthesises from its wavelet coefficients exactly since the wavelet coefficients capture all the information of band-limited signals.
This page outlines the main features of FLAGLET, installation details as well as the core functionalities and interfaces. References, version, and license information then follows. FLAGLET requires the FLAG, S2LET, SSHT and FFTW libraries.
The core functionalities of FLAGLET are written in C and are self-documenting. The C library requires FLAG, S2LET, SSHT and FFTW. Interfaces are provided for all high-level routines in Matlab. Several examples, tests and demos are provided fo the C library and the Matlab interfaces.
