cwtTh {Rwave} | R Documentation |
Compute the continuous wavelet transform with (complex-valued) Cauchy's wavelet.
cwtTh(input, noctave, nvoice=1, moments, twoD=TRUE, plot=TRUE)
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). |
moments |
number of vanishing moments. |
twoD |
logical variable set to T to organize the output as a 2D array
(signal size x nb scales), otherwise, the output is a 3D array (signal
size x noctave x nvoice).
|
plot |
if set to T , display the modulus of the continuous wavelet
transform on the graphic device.
|
The output contains the (complex) values of the wavelet transform of the input signal. The format of the output can be
2D array (signal size x nb scales)
3D array (signal size x noctave x nvoice)
tmp |
continuous (complex) wavelet transform. |
