VectGUI: A MATLAB-Based Simulation Tool [Testing Ourselves]

The vector analysis graphical user interface (VectGUI), a MATLABbased vector analysis visualization tool, can be used as a supplementary tool in the first course of electromagnetic education. The main purpose of this tool is to provide various visual aids that assist students in developing a mental image of some fundamental concepts in vector calculus and curvilinear coordinate systems. This tool is composed of seven subtools: two designed for the dynamic visualization of geometries in cylindrical and spherical coordinates; two used to display the scalar and vector fields; and three designed to demonstrate the gradient, curl, and divergence fields.
