Squeezed Continuous Wavelet Transform

Computes the synchrosqueezed continuous wavelet transform with the (complex-valued) Morlet wavelet.

Keywords

Usage
cwtsquiz(input, noctave, nvoice=1, w0=2 * pi, twoD=TRUE, plot=TRUE)
Arguments
input

input signal (possibly complex-valued)

noctave

number of powers of 2 for the scale variable

nvoice

number of scales in each octave (i.e. between two consecutive powers of 2).

w0

central frequency of the wavelet.

twoD

logical variable set to T to organize the output as a 2D array (signal size \(\times\) nb scales), otherwise, the output is a 3D array (signal size \(\times\) noctave \(\times\) nvoice).

plot

logical variable set to T to T to display the modulus of the squeezed wavelet transform on the graphic device.

Details

The output contains the (complex) values of the squeezed wavelet transform of the input signal. The format of the output can be

2D array (signal size \(\times\) nb scales),

3D array (signal size \(\times\) noctave \(\times\) nvoice).

Value

synchrosqueezed continuous (complex) wavelet transform
