Expand description
MATLAB-compatible fminbnd builtin for bounded scalar minimization.
fminbnd finds a local minimum of a scalar function on a finite interval
using Brent’s method (golden-section search combined with parabolic
interpolation). The implementation supports MATLAB’s four output arities:
x = fminbnd(fun, x1, x2)x = fminbnd(fun, x1, x2, options)[x, fval] = fminbnd(...)[x, fval, exitflag] = fminbnd(...)[x, fval, exitflag, output] = fminbnd(...)
The optional options struct (typically created by optimset) honours
TolX, MaxIter, MaxFunEvals, and Display.
