Hi,

I am having a problem for 2 months that Ux, Uy & Uz are the matrix of the coordinations.

Such as Ux,Uy & Uz = [ 1 2 3 4 5 ........]

I wanna plot the surface net within the known coordinations of the nodes that likes the uploaded picture as I had tried to use with surf function which is not my expectation.

Anyway, thanks for kindly help.

“mesh”, “surf” functions can be used to generate the surface plot. To get the desired results, make sure that the x, y and z are arranged properly. For more information refer to the below links
