How do I put this in a single matrix, along with the descriptors like "roof angle, "1", "2E",...etc. and use it for interpolation. Well I can get by using a single column matrix as a work around but I guess I want a more compact looking solution, if that makes sense.

I'm exploring Jean's and overlord's additional suggestion but still it was already solved for me. Another question is that would that still work if I had to do interpolation in both the column values and row values such as in case below. From what I understand, InterBilinear() seems incapable of doing what I aim to do. Do you have any suggestions?

Do you have any suggestions? On the contrary, InterpBilinear() does exactly what you seek. It interpolates both row and column values. PS: I added extra values to accommodate ≤ and ≥ boundaries.
