I wrote an event-driven program in MATLAB to generate a Graphical User Interface that could be used to graph a single function or superimpose multiple functions. The GUI included the following user interface controls: a function input, a function limit input, a grid push button, a legend push button, a hold push button, and a plot push button. This project required proficiency in the MATLAB programming language, an understanding of data structures, and an understanding of how to write callback functions.
