7: Zero-finding
( \newcommand{\kernel}{\mathrm{null}\,}\)
In this chapter we’ll use the MATLAB function fzero
to solve nonlinear equations. Nonlinear equations are useful for modeling physical systems; for example, in one of the exercises at the end of this chapter, you can use fzero
to find the equilibrium point of an object floating on water. Using fzero
is also an opportunity to learn about function handles, which we’ll need for the following chapters.
