I have had good experiences with Apple's vDSP primitives under OS X and iOS.

http://developer.apple.com/library/mac/#documentation/Accelerate/Reference/vDSPRef/Reference/reference.html

Now I am trying to port some code that relies on vDSP to Linux and I wonder if any equivalents are available built into one of the standard libraries.

  • You'll need to cherry pick from various libraries I think, e.g. FFTW, Intel IPP, OpenCV, etc, depending on what kind of routines you're using. – Paul R Feb 26 '13 at 19:05

While there is not presently any library that matches vDSP, there are several alternatives you might explore. A couple off the top of my head:

  • OpenCV is an impressive collection of image processing and computer vision routines with a vibrant user and research community.
  • Eigen is a C++11 template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

My personal recommendation would be Eigen.

  • I guess the reason, that there is no perfect Linux equivalent is the absence of [NEON SIMD engines](http://www.arm.com/products/processors/technologies/neon.php) in most devices. [Project Ne10](http://projectne10.github.io/Ne10/) is a suitable Android pendant though. – Maximilian Körner Jul 22 '14 at 13:31
