I am currently trying to write a code that will divide each iteration of a set data that only comprises of voltage values up into separate figures/entities after the last zero crossing of each iteration as well as record the first zero crossing of each. Within the provided figure (picture), one iteration is highlighted in red. Currently the data is only 10 iterations of an experiment, but I eventually want to record over 100 iterations and process the data through a MATLAB code. Any and all help is appreciated. Thank you.
