Object Scanning with MATLAB using the LEGO Infrared Sensor
This exercise is intended to help students to understand how to scan the relative distance of a 3D object from an infrared 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.

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. Continue reading “Missing Version History of MATLAB Functions [UPDATE: Fixed]”
