function val = rosenbrocksaddle(scale, params)%ROSENBROCKSADDLE  Standard optimization function for demonstration.%		VALUE = ROSENBROCKSADDLE(SCALE, PAR) returns the value of Rosenbrock's%		saddle at (PAR.parameter1, PAR.parameters2) scaled with input parameter%		SCALE. The absolute minimum of the function is at (1, 1).%%		Markus Buehren%		Last modified 03.02.2008 x = params.parameter1(1);y = params.parameter2(1);val = scale*((y-x.^2).^2+(1-x).^2);pause(0.1);
