So what kind of visualization do you want at the end? Do you want a surface? In which case you could do something like
x = 0:0.1:1;
y = -1:0.05:2;
[X,Y] = meshgrid(x,y);
params = [X(:),Y(:)];
n = size(params,1);
Z = zeros(n,1);
for k=1:n
Z(k) = myfunc(params(k,:),...);
end
Z = reshape(Z,size(X));
surf(X,Y,Z)
