I have a 3xN matrix, which represents N points in one curve. I know plot3 can plot this curve easily, but I want to use color to represent the curve orientation. For example, if the curve is in x direction, the color is "red", if the curve is in y direction, the color is in "green", if the curve is in z direction, the color is in "blue“.
So the color will vary with the curve going from the beginning to the end.
I saw some example from other software, want to know whether it can be done in matlab.
