Object Scanning with MATLAB using the LEGO Ultrasonic Sensor
This exercise is intended to help students to understand how to scan the absolute distance (in meters) of a 3D object from a ultrasonic sensor. The quality of the result, possible artefacts and sources of error are discussed in conjunction with the results of a previous exercise on the spatial resolution of the sensor.

Missing Version History of MATLAB Functions [UPDATE: Fixed]
One of the really missing things in MATLAB is a version history of specific functions. As a MATLAB user for 25 years, I have a lot of MATLAB code that contains functions that have been modified, exchanged, or completely disappeared. I am mainly concerned with functions from the Signal Processing Toolbox, but this can also be due to the fact that I use this toolbox the longest.
