Applies a one-dimensional zero-phase filter. filter_zerophase applies the filter, reverses the order of the resulting signal, applies the filter again, and reverses the signal a second time, resulting in zero-phase behavior. filter_zerophase works column-wise for matrices.
y = filter_zerophase(b, a, x)Legacy name: filtfilt
Forward filter coefficients. b is a vector.
Backward filter coefficients. If the first backward filter coefficient does not equal 1, MathScript normalizes the elements in a by the first backward filter coefficient. a is a vector.
Signal to filter. x is a real or complex vector or matrix.
Filtered signal. y is a real or complex vector or matrix.
X = 0:0.01:1; B = ; A = [1, 1, 1]; Y = filter_zerophase(B, A, X)
