TYhe problem persists. The issue is, i dont want the rise and fall time of the step response. I want the rise and fall time of the data itself. To do the ssest and then take the step response is not correct.
I am not trying to model a system and then see the step response of it. I want to see the rise and fall time of the data i have not the step response of the data i have.
That is the different.
Picture this, working with an o scope, when you do a single trigger and get a plot, you can hit the "measure"button on every scope on earth. You can select rise and fall time and it will go off and mark the rise and fall time of the plot.
its fine, i have given up. As with many many things in matlab, what should be easy and take 5 minutes in python takes 5 hours of frustration.
I have just given up trying to find this data. I tried to do something a bit more manual using poly fit and doing some calculus on it but in order to approximate the curve correctly i need to go out to the 10th order plus which makes doing this via derivitives uselss
Since i am giving up on this one, can you guys lend a hand with this new problem i have discovered. I am disapointed that i even have to ask this one.
