Implementing a refractive index profile matrix into comsol

Hi everyone, I want to do an mode analysis on a specific 2D structure. This 2D structure exists in the form of an refractive index profile-matrix, which has over 1000x1000 entries. This matrix has two values, one for each material used. If I would do a mesh plot in matlab with that matrix, I would get my refractive index profile.
Now the problem is, I am a greenhorn regarding comsol. Does someone know a method, how I could implement (or import) the matrix into comsol and use that matrix to build the geometry-profile?
I am using comsol 5.4.

Hello Richard,
It sounds like you should use an Interpolation function. See the COMSOL Multiphysics Reference Manual (Sorry, I can't tell you the exact page because I don't have 5.4 installed, but use Ctrl+F and you should find it easily), or various threads in this Discussion Forum.
Best,
Jeff

Jeff Dear Jeff,
Thank you very much for your answer. The Interpolation function was indeed what I was looking for. Still working on it, but I make progress. Have a nice day!
