As others have pointed out, VSIPL++ is 'as free' as FFTW. Both require a
commercial license if used in closed source apps.
Also note that Linux versions of Intel libs have an 'open' binary version
but do check licenses. Also note that I don't think you have to have
libraries like MKL/IPP or Mercury SAL (or ATLAS etc) but each may help you
get better performance on a particular platform than the vectorised basic
code your compiler might provide using VSIPL++ core without the libs.
Really depends what you want to do.
VSIPL++ was IMHO the best of the options I looked at for signal processing ~
1 year ago though I'd characterise it as 'evolving' and not as mature as say
Intel's MKL/IPP and equivalents.
