cwtpolar {Rwave} | R Documentation |
Converts one of the possible outputs of the function cwt
to modulus and phase.
cwtpolar(cwt, threshold=0)
cwt |
3D array containing the values of a continuous wavelet
transform in the format (signal size x noctave
x nvoice) as in the output of the function
cwt with the logical flag twodimension set to
FALSE.
|
threshold |
value of a level for the absolute value of the modulus below which the value of the argument of the output is set to -pi. |
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)
Modulus and Argument of the values of the continuous wavelet transform
output1 |
3D array giving the values (in the same format as the input) of the modulus of the input. |
output2 |
3D array giving the values of the argument of the input. |
