What is the reason?? Thank you, Irina Irina Foss Environmental Research Institute North Highland Coll...

wavelet parameters with sowas
Hello everybody. My name is Angela. I'm doing wavelet using the sowas library. The problem I have is that I don't know how to choose the paremeters to describes differnt wavelet analysis. How I select the noctave, nvoice, w0, s0,...? I hope my question is clear enough. Thank you very much beforehand.

Rwave cgt plot time axis problem
Dear helpers, When I use the function cgt of library Rwave, the time axis of the plot is always on the [0,1] scale regardless of the original time. This happedn when I tried to reproduce some pictures of "Practical Time-Frequency Analysis", e.g. Figure 3.5 and 3.6 using the codes provided in the book. But the figures of the book display the real sampling time using the same codes.
