I am working on basic signal processing problems in MATLAB. I have found a signal from the internet (i don't remember the site exactly). The data is organized in column wise. 1st and 2nd column is data and 3rd column is a rectangular wave. The rectangular wave is not very smooth. So I decided to detect four points as shown in the figure. I spend 2 days to find the exact solution but i couldn't find any solution to the detect those four points. I tried few things:
1) finding the difference between the points to get 1,2,3 and 4 points. but it doesn't work.
2) Median Filter to smooth the wave. 
Anyone, please give some suggestion to detect these points in MATLAB
