SmoothMeshLines2() stuck in infinite loop

[B137P107]

In the latest release v0.0.36 using Octave 10.2.0
The function SmoothMeshLines2() is used in AutoSmoothMeshLines(), and the latter is used in SmoothMesh().

By using the following set of values, SmoothMeshLines2() ends up by beeing stuck in while(1) loop (line 76) :
lines = [-22 -1.414 -0.25 0.25 1.414 2 22];
max_res = 14.99;
ratio = 1.5;
lines = SmoothMeshLines2(lines, max_res, ratio);

This can be easily avoided by making a slight change of the ratio, or by adding a line in the mesh.

Yes unfortunately all SmoothMeshLines method in Octave have flaws... But changing them is very dangerous too as it may change and break existing users/uses.

The much newer one in python is much more robust and much better... Maybe it could be "back-ported" to Octave?

Regarding SmoothMeshLines: "much newer one in python":

Is the slight difference of the results between "Simple_Patch_Antenna.py" versus "Simple_Patch_Antenna.m" caused by the changes in the smooth-mesh algorithms?

Simple_Patch_Antenna.m
FDTD simulation size: 49x49x43 --> 103243 FDTD cells

Simple_Patch_Antenna.py
FDTD simulation size: 49x47x45 --> 103635 FDTD cells

I'm surprised they are this close... yes both are meshed differently...
