Optimization

Minimum of single and multivariable functions, nonnegative least-squares, roots of nonlinear functions

Optimizers find the location of a minimum of a nonlinear objective function. You can find a minimum of a function of one variable on a bounded interval using fminbnd, or a minimum of a function of several variables on an unbounded domain using fminsearch. Maximize a function by minimizing its negative.

Find a nonnegative solution to a linear least-squares problem using lsqnonneg.

The equation solver fzero finds a real root of a nonlinear scalar function.

Control the output or other aspects of your optimization by setting options using optimset.

Solve problems and set options using a visual interface with the Optimize Live Editor task.
