The script should remove and interpolate missing points (NaNs) in column L_Angle. You can use any type of interpolation: replacing a NaN with the value from the previous row, linear interpolation, non-linear interpolation using polyfit function.
Illustrate results of your interpolation by plotting a small piece of data before and after interpolation on the same graph using the "plot" and "hold on" commands. Submit the script and the plot in a single Word file.
