Using MATLAB GUIs to Improve Student Engagement and Understanding [PDF]

open access: yes2018 UKACC 12th International Conference on Control (CONTROL), 2018
Laboratories are a core part of any engineering degree, but access to laboratories is typically limited due to a combination of timetable, space and equipment restrictions [1]. In more recent years that has been a significant growth in so-called virtual laboratories (VL), that is laboratory like activities that can be accessed via software or even a ...
