** Minimize a function of one variable. **

** FMIN('F',x1,x2) attempts to return a value of x which is a local **

** minimizer of F(x) in the interval x1 < x < x2. 'F' is a string **

** containing the name of the objective function to be minimized. **

** **

** **

** FMIN('F',x1,x2,OPTIONS) uses a vector of control parameters. **

** If OPTIONS(1) is nonzero, intermediate steps in the solution are **

** displayed; the default is OPTIONS(1) = 0. OPTIONS(2) is the termination **

** tolerance for x; the default is 1.e-4. OPTIONS(14) is the maximum **

** number of steps; the default is OPTIONS(14) = 500. The other components **

** of OPTIONS are not used as input control parameters by FMIN. For more **

** information, see FOPTIONS . **

** **

** **

** FMIN('F',x1,x2,OPTIONS,P1,P2,...) provides for up to 10 additional **

** arguments which are passed to the objective function, F(X,P1,P2,...) **

** **

** **

** Example: **

** fmin('cos',3,4) computes pi to a few decimal places. **

** fmin('cos',3,4,[1,1.e-12]) displays the steps taken **

** to compute pi to about 12 decimal places. **
