Function Summary

Function functions are functions that call other functions as input arguments. An example of a function function is fplot, which plots the graphs of functions. You can call the function fplot with the syntax

• fplot(@fun, [-pi pi])
  

where the input argument @fun is a handle to the function you want to plot. The function fun is referred to as the called function.

The function functions are located in the MATLAB funfun directory.

This table provides a brief description of the functions discussed in this chapter. Related functions are grouped by category.
