Matlab program to price a simple interest rate cap/floors

We need a Matlab script to price an examples of cap/floor in 3 days. Need to use the Financial Toolbox. This is intended for demonstration to students how to price interest rate derivatives in Matlab, so nothing fancy is needed!! Just some closed-form model (like Black's model), standard deviation as volatility, etc. Here is the cap/floor: cap/floor effective-10/09/09 09/30/16; if Libor3M > 4% receive Libor3M-2%, if Libor3M < 0.7% receive 4%-Libor3M, if not 0% We will give the Libor 3M, 6M, 9M, 12M data, swap rates for 3M Libor of 1 year, 2 year etc. data. Thank you for your interest!
