Hello everyone. I need a help to find the average of each vertical steps in a stepped sawtooth wave. For clarity, I have attached the figure of sawtooth wave. Just to reiterate how can I find the average of each small vertical steps in the attached stepped sawtooth wave? Thank you for the help in advance.

I would fit a line to the steps with polyfit, then find the intersections of the line fit with the vertical edges.

If you have the Signal Processing Toolbox, FINDCHANGEPTS is worth a look (it will give you the indices of each step of which you can take the average later -- see https://www.mathworks.com/matlabcentral/answers/313651-additional-findchangepts-function-output?s_tid=srchtitle for an example on how to extract each mean).

The example in "help findchangepts" should hopefully get you started.
If you post your data though, maybe another volunteer can come up with something even better!
