Edit: I do not understand the examples from the link:https://in.mathworks.com/help/curvefit/examples/constructing-spline-curves-in-2d-and-3d.html
Maybe anyone knows how to create more points using the cubic spline interpolation. For example a 3d size of 100x50x75 (x,y,z axis) into a 150x75x100. Thank you!
