extrapolate/interpolate 3D table data in Simulink (like ScatteredInterpolant in MATLAB)

I wrote MATLAB code where I need to extrapolate/interpolate data:

         x =            y =         z =            
    
         1     2        5     6        9    10
         3     4        7     8        11   12

Where

z=F(x,y)

so, if

x=1 & y=5 -> z=9

Since I wanted to get other points inside and outside the table I used `scatteredInterpolant`.

Now I want to remake my code in Simulink, but I discovered that `scatteredInterpolant` isn't supported.

How can I achieve this in Simulink?
