    Computes the phase delay vector and the frequency vector of a filter. If you do not request an output, this function plots the phase delay of the filter in the current plot window. phasedelay(b) is equivalent to phasedelay(b, [1], 512). phasedelay(b, a) is equivalent to phasedelay(b, a, 512).


    phasedelay(b, a)
    phasedelay(b, a, w)
    phasedelay(b, a, w, fs)
    phasedelay(b, a, n)
    phasedelay(b, a, n, 'whole')
    phasedelay(b, a, n, fs)
    phasedelay(b, a, n, 'whole', fs)
    h = phasedelay (b)
    h = phasedelay (b, a)
    h = phasedelay (b, a, n)
    h = phasedelay (b, a, n, 'whole')
    h = phasedelay (b, a, n, fs)
    h = phasedelay(b, a, w)
    h = phasedelay(b, a, w, fs)
    [h, f] = phasedelay(b)
    [h, f] = phasedelay(b, a)
    [h, f] = phasedelay(b, a, n)
    [h, f] = phasedelay(b, a, n, 'whole')
    [h, f] = phasedelay(b, a, n, fs)
    [h, f] = phasedelay(b, a, n, 'whole', fs)



    Numerator coefficients of the filter. b is a vector.


    Denominator coefficients of the filter. a is a vector.

    Default: [1]


    Frequency points at which you want to evaluate the phase delay. If you do not specify w, MathScript evaluates the phase delay at n points equally spaced around the upper half of the unit circle. w is a vector.


    Sampling frequency in Hz. fs is a scalar.


    Number of frequency points. n is a positive integer.

    Default: 512


    Directs MathScript to evaluate the phase delay at n points equally spaced around the unit circle.



    Phase delay vector of the filter. h is a real vector.


    Discrete frequency vector, in radians/sample, that corresponds to h. f is a vector.

    b = [1, 2];
    a = [-1, 1, 1, 3];
    n = 32;
    [H, F] = phasedelay(b, a, n)
