| Dear all, I have a current data over the water column at a particular station. To understand the period present in this time series, what I did as the following: let fftv=ffta(v) fill fftv but this gives amplitude in terms of depths vs frequencies. My interest is to make a fill plot in terms of depth and period, instead of frequencies. I could not succeed to regrid it in days. Is it possible to resolve this issue. Thanks in advance Regards, Abhisek Chatterjee POD, NIO Dona Paula Goa-403004 Ph.N- +91-9371679339 |
