Fitting a Step/Stair Function to data...

I have two vectors of data, each of somewhat significant size (1x784), that I wish to curve fit. I have the curve fitting toolbox, if that helps. Context: This data is from an exoplanet transit. One vector is the brightness of the star in magnitude and the other is time in UTC hours, so when plotted you get a brightness over time curve. There is a slight dip in the center, and this is what I wish to show from the step/stair function. I've tried fourier, but it looks too gradual, too smooth. Is there a way to fit a stair/step function to the data?

Hi Kylie,
You can follow the approach presented in this File-exchange submission to fit curves to data with a sudden discontinuity.
Hope this helps!
