Hi! I am wondering if it is possible to use a function similar to contour with more dimensions.
I usually use contour with two matrixes of coordinates X and Y (generates with meshgrid, ''grid_X'' and ''grid_Y'') and an interpolated function (generate with griddata)
[C,h] = contour(grid_X,grid_Y,int_function);
When I am in a 2D geometry it works. However, I need one more dimension now i.e. I have to use X,Y,Z and an interpolated function as contour function.
Is there a function similar to ''contour'' (or a method) to use in this case?
As an example of what I want I show the following image in which I have the coordinates of the sphere grid_X, grid_Y and grid_Z (all of them with dimensions 101 x 101 x 101) and the surface to generate the contours int_function with dimensions 101 x 101 x 101 as well.

Thanks for your answer, I tried it but I think that it is not the solution that I am looking for.

All your matrices are 3d, i suppose you have data to display volume? Can you explain more? WHat are you trying to achieve?

I would use contour3 to plot contours in 3D. I have no idea if it would reproduce the figure in your Question, however it is definitely the place to begin. Another function that could be useful to get a similar result is rotate.
