Exporting image-generated geometry in matlab to FEA compatible format

Hello, I am doing an undergraduate thesis, and I like to implement MATLAB in some of the analysis.
The query is, how to export a file generated as an image in a code, to a format compatible with FEA (Finite element analysis).
The goal is to find the temperature profile in this slag pot geometry, which is a truncated cone.
So, once having the compatible geometry I can use matlab pdegplot and some commands related to find the temperature profile.
The code was generated by AI (Claude).
