Ok, I tried with R2017a and cwt() worked. I have another question though.
I used this:
cwt(data,hours(1),'morse'); % The sampling interval is 1 hour
However, the axes are weird. The horizontal axis was fine (hours). For the vertical axis y-values themselves, i understand the graph is scaled by pow2(). The values where the magnitudes are high correspond to what I expect (i.e. around 25 and 12.5), but these are supposed to be in days, whereas the plot axis is in hours. How can I convert to the proper units with days in both axes? I suspect my definition of
duration() (i.e. hours(1))
Any advice please?
