Squeezed Continuous Wavelet Transform
Computes the synchrosqueezed continuous wavelet transform with the (complex-valued) Morlet wavelet.
cwtsquiz(input, noctave, nvoice=1, w0=2 * pi, twoD=TRUE, plot=TRUE)
input signal (possibly complex-valued)
number of powers of 2 for the scale variable
number of scales in each octave (i.e. between two consecutive powers of 2).
central frequency of the wavelet.
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).
logical variable set to T to T to display the modulus of the squeezed wavelet transform on the graphic device.
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).
