有PDL的信号处理模块吗？
Perl数据语言是否有类似于Matlab信号处理工具箱？我知道 PDL::FFT(W)，但找不到任何用于滤波器构造或统计属性估计的函数。
Is there a module for the Perl Data Language that is similar to the Matlab signal processing toolbox? I'm aware of PDL::FFT(W), but can't find any functions for filter construction or estimation of statistical properties.

唉，不。虽然您可以通过自己的卷积、叉积等组合来实现与 Matlab 信号处理工具箱相同的目标，但没有人使用 PDL 编写全面的信号处理工具包。 PDL 最初是 IDL 的竞争对手，因此其最强的绑定集中在图像处理上。
如果您正在考虑制作自己的工具箱（这太棒了！），我建议您使用 PDL::TimeSeries。
Alas, no. While it is likely that you can accomplish the same ends as Matlab's signal processing toolbox with your own combination of convolutions, cross products, etc, nobody has written a comprehensive signal processing toolkit with PDL. PDL started as a competitor to IDL, so its strongest bindings focus on image manipulation.
If you are considering making your own toolbox (which would be FANTASTIC!), I would suggest PDL::TimeSeries.
现在至少有 https://metacpan.org/pod/PDL::DSP: :Fir 用于有限脉冲响应滤波器内核。
There is now at least https://metacpan.org/pod/PDL::DSP::Fir for finite impulse response filter kernels.
PDL::Audio 有滤波器（包括 FIR 滤波器，又名卷积） 。我确信它远没有 Matlab 工具箱功能齐全，而且它有很多你可能不感兴趣的东西（毕竟它是为发出声音而设计的），但它至少可以做一些你想做的事情。想。
如果我制作这个模块，我会将其称为 PDL::DSP。
PDL::Audio has filters (including FIR filters, aka convolution). I'm sure it's nowhere near as full-featured as the Matlab toolbox, and it has lots of stuff you're probably not interested in (it's designed for making sound, after all), but it will do at least some of what you want.
If I were making this module, I'd call it PDL::DSP.
