What Is Optimization Toolbox?

fminbndPurposeEquationFind minimum of single-variable function on fixed intervalFinds a minimum for a problem specified bywhere x, x 1,andx 2are scalars and f(x) is a function that returns a scalar.SyntaxDescriptionx = fminbnd(fun,x1,x2)x = fminbnd(fun,x1,x2,options)[x,fval] = fminbnd(...)[x,fval,exitflag] = fminbnd(...)[x,fval,exitflag,output] = fminbnd(...)fminbnd attempts to find a minimum of a function of one variablewithin a fixed interval.x = fminbnd(fun,x1,x2) returns a value x that is a local minimizerof the scalar valued function that is described in fun in the intervalx1 < x < x2. fun is a function handle for either an M-file functionor an anonymous function.x = fminbnd(fun,x1,x2,options) minimizes with the optimizationoptions specified in the structure options. Useoptimset to set theseoptions.[x,fval] = fminbnd(...) returns the value of the objective functioncomputed in fun at the solution x.[x,fval,exitflag] = fminbnd(...) returns a value exitflag thatdescribes the exit condition of fminbnd.[x,fval,exitflag,output] = fminbnd(...) returns a structureoutput that contains information about the optimization.“Avoiding Global Variables via Anonymous and Nested Functions” onpage 2-20 explains how to parameterize the objective function fun, ifnecessary.8-28
