Introduction to Advanced Functions

There are several useful built-in Matlab functions that deserve special mention and additional discussion regarding their usage in Matlab. These functions are covered in this module.

A key feature of each of these Matlab functions, is that they require defining other functions which are then used by the built-in function to solve problems.

The built-in functions that are covered in this module are:

• fzero - returns the nearest root of a function
• quad - returns the approximate area under a curve
• ode45 - returns points that solve a system of ODEs
• fcnchk - returns a handle to a function
