MATLAB: How to contour of 4D matrix

Question

Please help. I have a 4D matrix (4 columns x 8000 rows) of x, y, z, coordinates and c=f(x,y,z). The data when plotted looks like the image, with the value of c by color.

My question is: how do I interpolate a contour of c=0? In this case, the contour should be a surface shape, and I would like to get that surface of zero values. I attached the file Data.txt so the data can be looked at.

Thanks so much!

Answer 1

You could use isosurface and later plot the resulting surface
