How can I interpolate in matrices with NaN elements in Simulink?

Hi There,

I would like to use a 2-d lookup-table, add a 7d-matrix to it and have it interpolate everything between the given values. So far, that works, but unfortunately my 7d-matrix has some NaNs in some Elements, which cause the interpolation to fail.

Example with 2d-Matrix:

A = [1 2 3; 2 NaN 4; 3 4 5]

if I give the lookup table the inputs 1.5 and 2.5, I want it to return 3.

Now, how could I go about achieving this?

Many thanks in advance

Any update on this ?
