I have this code which as it supposed to but I need something different.
Is it possible to overlay map for example map of the world or regional map like a continent, in this code?
Please help if it is possible
[X,Y,Z] = meshgrid(-2:.2:2);
V = X.*exp(-X.^2-Y.^2-Z.^2);
xslice = [];
yslice = [];
zslice = [-2,0,2];
slice(X,Y,Z,V,xslice,yslice,zslice)
ax=gca;
ax.Children(1).LineStyle='none';
ax.Children(2).LineStyle='none';
ax.Children(3).LineStyle='none';
view(15,15);
colormap jet

Example
A = imread('ngc6543a.jpg');
[m,n,~] = size(A);
N = 100; % number of points for surface
Z = peaks(N); % create peaks
x = linspace(0,1,N);
image(A)
hold on
Zscaled = (Z-min(Z(:)))/(max(Z(:))-min(Z(:)))*255;
p = pcolor(x*n,x*m,Zscaled);
hold off
set(p,'FaceAlpha',0.3)
set(p,'EdgeColor','none')
saveas(gca,'test.png')

Thanks for your answer but what I want is to overlay maps on each of the slice as it is
