hello.. i juz wanna ask , using this function how to plot its 2D graph?
function f = dropwavefcn(x)
if strcmpi(x,'init')
f.PopInitRange = [-2;2] ;
f.KnownMin = [0 0] ; % For plotting purposes only
else
if size(x,2) > 2
warning('psopt:demos:toomanydims',...
'Only using first two dimensions of search space')
elseif size(x,2) < 2
error('Drop Wave Function requires two dimensions')
end
x = reshape(x,1,[]) ;
f = -(1 + cos(12*norm(x(1:2))))/(0.5*x(1:2)*x(1:2)'+2) ;
end
i really need the answer as soon as possible...thanks for your concern
