Import geometry from Matlab into Comsol

Hello,


First of all, I want to emphasize that I am a beginner with Comsol.

I am trying to import a geometry generated with Matlab into Comsol in order to study the wave propagation in this geometry.

My geometry is simply a n*n matrix, with 2 values : 0 and 1. The value 1 is the material and the value 0 is the air inside the material.

How can I import this matrix into Comsol to work with ?

Thank you for helping out.
