I would like to determine the location at which there is data variation (like the highlighted points in the attached image).
Kindly find the attached code + .mat file.
Each sub-plot represents a variable on y-axis and the time on x-axis. Usually, the variation appear in several variables (plots) like this one.
Could you suggest the best method to do so?
and How can I determine the starting and ending points of that variation?
I appreciate your help.
