Numerical Integration GUI

A GUI for plotting and evaluating the integral of statistical and f(x) functions.

This GUI can be used by entering 'nu' at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot over a user defined range. The function's integral can be evaluated over a user defined range by using: The composite trapezium, simpsons and gauss-legendre rules. This is useful for calculating accurate probabilities that one might see in statistical tables.
