Minimizing Functions and Finding Zeros

MATLAB provides a number of high-level function functions that perform optimization-related tasks. This section describes:

• Minimizing a function of one variable
• Minimizing a function of several variables
• Setting minimization options
• Finding a zero of a function of one variable
• Converting your code to MATLAB Version 5 syntax

The MATLAB optimization functions are:

fminbnd	Minimize a function of one variable on a fixed interval
fminsearch	Minimize a function of several variables
fzero	Find zero of a function of one variable
lsqnonneg	Linear least squares with nonnegativity constraints
optimget	Get optimization options structure parameter values
optimset	Create or edit optimization options parameter structure

For more optimization capabilities, see the Optimization Toolbox.
