cwtftinfo2

Supported 2-D CWT wavelets and Fourier transforms

Syntax

Description

example

cwtftinfo2 lists the supported 2-D continuous wavelet transform (CWT) wavelets and corresponding parameters for use with cwtft2.

example

cwtftinfo2(wname) displays the equation for the 2-D Fourier transform of the wavelet, wname. The figure with the 2-D Fourier transform of the analyzing wavelet has a drop-down list from which you can select other wavelets.

Examples

Display the Expression for the 2-D Fourier Transform

Display the expression for the 2-D Fourier transform of the Cauchy wavelet.

cwtftinfo2('cauchy')

After displaying the Fourier transform for any wavelet, you can use the drop-down list in the bottom left to view the Fourier transform for any supported wavelet.

Input Arguments

wname — Wavelet namestring

Wavelet name, specified as a string. The following table lists the supported wavelets for the 2-D CWT and associated parameters:
