我在哪里获得FFT,如果仅使用实数输入则可以 [英] Where do I get FFT, is ok if it uses real inputs only
问题描述
我需要一个超快的fft功能。输入是采样波形,因此所有输入值都是实数。结果,当然,将是
复杂。
也需要它来自免费资源。

和 ; comp.lang.c ++"只是尖叫着你这是获得fft的地方
功能,超快和免费,对吗?我们也可以为你包装吗?
转到网络搜索引擎并在那里进行研究。如果您有C ++
_language_问题,请回来询问。

拿一个看看
C ++ Scalar,Vector,Matrix和Tensor类库

实际上,我刚刚来到来自多次搜索C ++ FFT的
最好的是使用谷歌8次点击 - 一次击中锻造组
和七次点击同样的电子邮件发布在不同的位置。
但是,谢谢你的值得建议。

I need a superfast fft function. The input is a sampled waveform so
all the input values will be real. The result, or course, will be
complex.
Need it to be from free source, too.

And "comp.lang.c++" just screams to you "this is the place to get an fft
function, superfast and free", right? Shall we gift-wrap it for you too?
Go to a web search engine and do your research there. If you have a C++
_language_ question, come back and ask it.

Take a look at
The C++ Scalar, Vector, Matrix and Tensor class Library

Actually, I just came from multiple searches for C++ FFT''s
The best was using google with 8 hits - a single hit to the forge group
and seven hits to the same email posted at different locations.
But thank you for your worthwhile suggestion.
