Find minimum of unconstrained multivariable function using derivative-free method

Nonlinear programming solver that searches for the minimum of a problem specified by

$$\underset{x}{\mathrm{min}}f(x)$$

*f*(*x*) is a function that
returns a scalar, and *x* is a vector or a matrix;
see Matrix Arguments.

finds
the minimum for `x`

= fminsearch(`problem`

)`problem`

, where `problem`

is
a structure. Create `problem`

by exporting a problem
from Optimization app, as described in Exporting Your Work.
