Usage:

plotfunction(fcn,LB,UB,varargin)

EXAMPLES:
1. plotfunction(@hosaki,[0 0],[5 5]);
% Plot hosaki function in the range of 0 - 5 in both dimension.

2. LB = zeros(1,4);UB= 10*ones(1,4); xypar = [2 3];
plotfunction(@shekel,LB,UB,xypar);
% Plot shekel function in the range of 0 - 10 in second and third dimension while keeping constant value (average of 0 and 10) in other dimensions.

3. baseValue = [3.2 4 4 6.8];
plotfunction(@shekel,LB,UB,xypar,baseValue);
% Plot shekel function keeping constant value of 3.2 in first dimension and 6.8 in last dimension. Here values in second and thirs dimension is overwriten by range of LB and UB as done in example 2.

4. For example you have the following function
f = parameterized_rosenbrock(x,a,b)
x1 = x(1);
x2 = x(2);
f = a * (x2 - x1^2)^b + (1 - x1)^b;

% Use the following to visualise the above function
LB=[-5 -2];UB=[5 8];
a = 100; b = 2; % additional argument to the function
plotfunction(@parameterized_rosenbrock,LB,UB,[],[],a,b)
