realifft

Version:
    Last Modified: March 15, 2017

    Computes the inverse fast Fourier transform (IFFT) where the output is known to be real.

    Syntax

    c = realifft(a)
    c = realifft(a, b)
    c = realifft(a, b, d)
    c = realifft(a, [], d)

    Inputs

    a

    Vector or matrix.

    b

    Controls zero-padding to the signal. b is an integer and typically is a power of 2.

    d

    Dimension of a in which MathScript performs the IFFT. d is an integer.

    []

    Tells MathScript that you want to specify a and d but not b.

    Outputs

    c

    Real inverse fast Fourier transform of a. If a is a vector, c = realifft(a) returns the original real inverse discrete Fourier transform (IDFT). If a is a matrix, c = realifft(a) returns the column-wise real IFFTs of all columns of a. c is a vector or matrix.

    A = [10, -2+2i, -2, -2-2i];
    C = realifft(A, 8)
