Could you please help me to plot a curve/arc(in 3D) with its center passing through the origin using MATLAB code?

This is a Comsol Multiphysics forum. Are you using Comsol Multiphysics? You can do a lot of MATLAB operations within Comsol Multiphysics, but for MATLAB support, see the links at: https://www.mathworks.com/matlabcentral/?s_tid=gn_mlc or look in your MATLAB help system.

Added later: I've begun to wonder if I may have misunderstood your problem. I initially assumed that you sought to plot a curve/arc (just as you said), but did you really seek to create/build a geometric curve/arc (a 1D geometry structure) within a 3D Comsol working geometry, and specifically to do so by means of Matlab commands (e.g., via LiveLink for Matlab) rather than directly by Comsol's GUI? The difference in meaning here is substantial: In one case, you are simply plotting a mathematical curve for you to look at. In the other case, you are creating/building a geometric object.
