I have a 3D matrix of 27 components of an eigenvector which are field values on a 3x3x3 grid of points. I want Matlab to plot level surfaces of the field values so I get some nested level surfaces. Can anyone help?
n = 5;
G = numgrid3d(n);
A = delsq3d(G);
size = (n-2)^3;
[V,D] = eigs(A,size);
for i = 1:size
temp = V(i,:);
temp = reshape(temp, [3,3,3]);
figure(i)
plot = surf(temp(1,:,:),temp(:,1,:));
shading interp;
end

isosurface(temp, LevelValueGoesHere)
but you will not see anything useful with a 3 x 3 x 3 area.
