The library is implemented in +portable C99 and provides an interface that can be easily accessed from other +programming languages such as C++, Fortran, Python etc. Generally, libsharp's +performance is at least on par with that of its predecessor; however, +significant improvements were made to the algorithms for scalar SHTs, which +are roughly twice as fast when using the same CPU capabilities. + +Supporting paper is availalbe at https://arxiv.org/abs/1303.4945") + (license license:gpl2+))) + (define-public psfex (package (name "psfex") |
