WebFeb 6, 2012 · Fminsearchbnd is used exactly like fminsearch, except that bounds are applied to the variables. The bounds are applied internally, using a transformation of the variables. (Quadratic for single bounds, sin (x) for dual bounds.) The bounds are inclusive inequalities, which admit the boundary values themselves, but will not permit WebThe fminsearch algorithm uses a special initial simplex, which is an heuristic depending on the initial guess. The strategy chosen by fminsearch corresponds to the -simplex0method flag of the neldermead component, with the "pfeffer" method.
