ichirpzt

Version:
    Last Modified: March 15, 2017

    Computes the inverse Chirp-Z transform.

    Syntax

    e = ichirpzt(a)
    e = ichirpzt(a, b)
    e = ichirpzt(a, b, c)
    e = ichirpzt(a, b, c, d)
    Legacy name: iczt

    Inputs

    a

    Vector or matrix.

    b

    Length of the transform. b is an integer.

    Default: length(a)

    c

    Complex ratio (complex scalar) used in the Inverse Chirp-Z transform. Depending on the magnitude of c, MathScript generates either arcs or spirals as sampling points.

    Default: exp(-2*pi*j/b)

    d

    Starting point (complex scalar) of the Inverse Chirp-Z transform.

    Default: 1

    Outputs

    e

    Inverse Chirp-Z transform of a. If a is a matrix, e returns the column-wise Inverse Chirp-Z transforms of all columns of a. e is a vector or matrix.

    A = [1, 2, 3, 4, 4, 3, 2, 1]
    C = chirpzt(A, 8)
    D = ichirpzt(C, 8)
