Uses FFT-filter coefficients to filter a signal. filter_fft works column-wise for matrices. If x and f are matrices of the same size, this function works column-wise for both x and f.
y = filter_fft(f, x)
y = filter_fft(f, x, n)Legacy name: fftfilt
FFT filter coefficients. f is a vector or matrix.
Signal you want to filter. x is a real or complex vector or matrix.
Minimum number of points in the FFT. n is a positive integer.
Filtered signal. y is a real or complex vector or matrix.
F = [1, 2, 1, 7]; X = 0:0.1:1; Y = filter_fft(F, X)
