Hi all, Discussion on [EMAIL PROTECTED] indicates octave performance on cygwin can be improved by linking with the fftw library, which is a state-of-the-art package for fast fourier transforms. Accordingly, I am proposing cygwin packaging for fftw-3.0.1, which is the current version.
Setup.hint would look like: ===================== @ fftw3 sdesc: "Library for computing Fast Fourier Transforms" ldesc: "fftw3 computes Fast Fourier Transforms in one or more dimensions. It is extremely fast. This package contains shared libraries for double precision." category: Math Libs requires: cygwin ===================== Although fftw3 can be built with both single and double precision versions, octave only uses double precision, so that is all I propose to build. Only a shared library (dll) will be built; no static library will be provided. I have verified that octave can properly detect the presence of fftw during its configuration, and can link with the shared library. Although it would be possible to provide headers and documentation in a separate package from the library, I do not propose to do so, preferring to stay with the simplicity of a single binary package built from a single source package for now. Assuming the proposal is successful and the packaging is accepted, a new version of octave, linked to the fftw library, would be released. The octave setup.hint would be modified to require fftw. Comments welcomed. Jim Phillips
