Computing mean of each step in measurement data

Hi everyone,
I have measurement data ‘measurement_data.mat’. I would like to compute the mean at each step where the value is not changing by a huge value. By eyeballing the plot of the data for the first column, it can be seen there are 125 steps. After computing the mean at each step I would like the data to finally be a matrix of 125x4 from being a matrix of 17850x4.
I have tried taking the mean of every n elements to get a meaningful result but it hasn't worked. The step size is not consistent all through.
Any kind of help or suggestion will be appreciated.
Thanks in Advance.

Try movmedian() where the window width is the width of your step width. The median filter removes noise while keeping edges sharp.
