Interactive Efficient Frontier Viewer

Demonstrates the use of MATLAB's nested functions to create graphical tools with little coding. This example creates an efficient frontier from supplied data (or generates random returns if no inputs are supplied) and then allows the user to move a crosshair along the efficient frontier to view the weights for the selected portfolio.

This example is similar in functionality to "Efficient Frontier GUI" but the code is less intimidating for new users. It invokes the "portopt" function from MATLAB's Financial Toolbox to create the efficient frontier.
