You can then determine the variance along each of those vectors and plot an ellipsoid which represents …Specify True Colors for Surface Plot. Specify the colors for a surface plot by including a fourth matrix input, CO. The surface plot uses Z for height and CO for color. Specify the colors using truecolor, which uses triplets of numbers to stand for all possible colors. When you use truecolor, if Z is m-by-n, then CO is m-by-n-by-3.I have a meshed annular region (shown in image), I have no a analytical function z=f (x,y)but a matrix A stored z value of each node. furthermore, I know coordinates of every element in A matrix.
