事实上 R2021b 也增加了一波支持 gpuArray 的对象 (filtfilt、pspectrum、downsample、resample、upfirdn、upsample、xspectrogram、shiftdata、unshiftdata)。 有大量数据需要处理,觉得 CPU 跑这些太慢的,不妨搞一块 GPU,试试把普通数据用 gpuArray 放...

filter:利用递归滤波器(IIR)或非递归滤波器(FIR)对数据进行数字滤波; fftfilt:利用基于FFT的重叠相加法对数据进行滤波,只适用于非递归滤波器(FIR); filter2:二维FIR数字滤波; filtfilt:零相位滤波(IIR与FIR均可) 滤波器特性分析: 脉冲响应Impz: 等价于使用函数filter输入一个脉冲信号x=[1;zero(N-1,1)]。 ...

To accelerate my FEX submission FiltFiltM, I've implemented a filter as C-Mex, which works in reverse order. To my surprise this was faster than running Matlab's FILTER forward, e.g. 3.7 times for a [10000 x 1] vector, 5th order Butterworth filter (Matlab 2009a, WinXP 32 bit, sing...
