There seems to be a problem with the addvertex function in R2022a. It works fine in R2021a.

There is a problem in how I can add new vertices to an existing model, where this is some inconsistency in passing 2D and 3D vertices to the addVertex function.

Sometimes, it seems there is a problem on how the function wants 2D inputs and sometimes 3D inputs.

Here's a sample. How can it take the first vertex and not the second one?

pgon = polyshape([1 1 2 4], [1 4 4 1]);
tr     = triangulation(pgon);
pdmodel  = createpde;
g = geometryFromMesh(pdmodel, tr.Points', tr.ConnectivityList');
addVertex(g,'Coordinates',double([1.66,4.00; 1.33,4.00])); % This works
addVertex(g,'Coordinates',double([1.00,3.00; 1.00,2.00])); % This throws an error
Error using pde.DiscreteGeometry/addVertex
Coordinates value must be a 3-column double matrix not containing Inf, NaN, or complex numbers.
