filter_fft

Version:
    Last Modified: March 15, 2017

    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.

    Syntax

    y = filter_fft(f, x)
    y = filter_fft(f, x, n)
    Legacy name: fftfilt

    Inputs

    f

    FFT filter coefficients. f is a vector or matrix.

    x

    Signal you want to filter. x is a real or complex vector or matrix.

    n

    Minimum number of points in the FFT. n is a positive integer.

    Outputs

    y

    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)
