Hello all, new MatLab user here, find the tutorials and documentation very useful so far! I am trying to evaluate the performance of a freezer in my lab. I wish to know the rate at which it cools back down to its setpoint after a spike in temperature. I want to be able to determine these rates for events over two years
I’ve been able to import the data into matlab as a table with the datetime and temperature, and then use the "find local extrema" task to identify the peaks. But I am now stuck on how I can find the rates of change after these peaks in an automated fashion. I also converted the data into timetables and tried doing this in the Signal Analyzer app. Would anyone be able to point me in the right direction?

I’ve included a plot to provide an idea of the data I’m working with. This plot has ~250,000 data pointsHello all, new MatLab user here, find the tutorials and documentation very useful so far!
