Until Java can beat C/Fortran in FFTs and SVDs, it's too slow for me. Show me FFTW in Java please. Where's the Java LAPACK?

- discardaccount 13y agoBtw, I would rather program in Java, but it IS too slow. (and idiomatic Java uses too much memory...)

- discardaccount 13y agoThank you for the link, but the benchmarks at the bottom of that page show that JTransforms is almost always slower than FFTW, and in only a few cases is it marginally faster. Benchmarks are always questionable, and I really wish they had compared single threaded performance, but I think this shows that Java still has some catching up to do before anyone should be called foolish for thinking C is faster.
