Is ssq_cwt designed for negative frequency analysis?

[aspirin-1218]

Hello,

First of all, thank you for sharing the great work.

I am trying to do time-frequency analysis on radar doppler signals (complex valued) and thus being able to analyze negative frequency really matters. We've experimented STFT and would like to test with CWT. After checking the ssq_cwt, I am not sure if we are able to analyze negative frequency with that. Could you please give us a simple example if I misunderstood the usage of ssq_cwt?
