Hi, Here I have a 2-D (x row X 3 column) matrix which represents a 3-D surface, each column represents the data of one axial. Now I want the intersection curve of the given surface and a surface parallel to the coordinate surface, for example, a surface parallel to YZ and the X value is 5. Can anyone help?

Did you try triscatteredinterp()?

Yes, I've tried to use triscatteredinterp to generate 3 2-D matrix to plot the surface, but don't know how to generate the intersection curve I need. more detail please.
