What code should I use to plot a 3D contour plot? I saw there are some contour3 functions, but I don't know how to create the 2*2 matrix for my data. I have data include (x,y,z) positioning data and value at each position. I attached part of my data looks like, not all y,z values are zero.
I also attached a plot that shows closely to what I want, but I also want scales shown on the figure.
