##### Squeezed Continuous Wavelet Transform

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

Keywords
ts
##### 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
