Good color scheme to represent 3 surfaces in one plot
Show older comments
I am trying to get a good color scheme to represent 3 surfaces in one graph, however I am not very experienced in this kind of stuff. I am asking if someone with more experience with plot functions in matlab can help me to get the 3 surfaces nicely highlighted.
I leave the code below (the IV, IV1 and IV2 matrices are so long because originally those data are obtained through a numerical procedure).
