Hello everyone,
I need help on a specific topic on Matlab.
I need to import on Matlab a meshed sphera created in Rhino7 and to insert in Matlab an axis passing through that sphera.
How can I insert the axis?
Thank you in advance

mesh=readSurfaceMesh('Analisi Matlab')
readSurfaceMesh requires Lidar Toolbox.
Looks as though the Lidar TB isn't available to the Answers forum interactive session....

You can use quiver3. In the example below I plot the 3 coordinate axes, you can modify accoridng to your vectors
clear variables, close all
% unzip
% load stl file
tri = stlread('Sfera.stl');
% plot triangulation
figure, axis equal, hold on
view([1 1 1])
% plot three coordinate axes
vx = [1 0 0];
vy = [0 1 0];
vz = [0 0 1];
quiver3([0 0 0],[0 0 0],[0 0 0],... % starting points
[vx(1) vy(1) vz(1)],[vx(2) vy(2) vz(2)],[vx(3) vy(3) vz(3)],... % vectors
10,... % scaling
'filled','LineWidth',3); % appearance params
