Calculate the diffusion coefficient for the following data set using a moving window mean squared displacement. Include your plot for MSD vs. time step with appropriate error bars, trendline, and equation. (Hint: This can be tedious to do by hand or on excel, but Matlab can be a useful tool for implementing for loops to do the analysis.) Use Matlab or Excel, Provide the code and all the formulas used.
