ichirpzt (MathScript RT Module Function)
Owning Class: transforms
Requires: MathScript RT Module
Syntax
e = ichirpzt(a)
e = ichirpzt(a, b)
e = ichirpzt(a, b, c)
e = ichirpzt(a, b, c, d)
Legacy Name: iczt
Description
Computes the Inverse Chirp-Z transform.
Inputs
| Name | Description |
|---|---|
| a | Specifies a vector or matrix. |
| b | Specifies the length of the transform. b is an integer. The default is length(a). |
| c | Specifies the complex ratio (complex scalar) used in the Inverse Chirp-Z transform. Depending on the magnitude of c, LabVIEW generates either arcs or spirals as sampling points. The default is exp(-2*pi*j/b). |
| d | The starting point (complex scalar) of the Inverse Chirp-Z transform. The default is 1. |
Outputs
| Name | Description |
|---|---|
| e | Returns the 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. |
Examples
A = [1, 2, 3, 4, 4, 3, 2, 1]
C = chirpzt(A, 8)
D = ichirpzt(C, 8)
