3D vector field simulator GUI

VECTGUI is an esay-to-use 3D vector field simulator with a friendly GUI. It can visualize the vector field, calculate divergence and also plot the curl of the field, all in one single GUI. All you need to do is to enter the symbolic expression for x,y and z component of the vector field, specify the ranges for x, y and z coordinates and push the Draw button.

Example:

>> vectgui
% Simply opens GUI but does not return anything to workspace.

>> H = VECTGUI;
% Opens GUI and also returns a cell array H to workspace. H contains coordinates of data points, corresponding vector components, divergence, and curl of the vector field. It also contains the handles of the two axes where vector field and its curl are plotted.
