n-D Lookup Table interpolation method and table output dimension

Hello,

I am using an n-D Lookup Table in my Simulink model and I have a problem with the table input and output dimensions with the spline interpolation. It is not possible to get a vector output with spline interpolation. I have an NxMx3 dimensional table and I would like get [1x3] vector output. There is not any problem if I use linear interpolation but I am forced to use 3 n-D lookup tables separating the pages to each of them for spline interpolation. Is this some kind of bug or a limitation with spline interpolation?

This is expected behavior.

The documentation says "If you select Cubic spline, the block supports only scalar signals. The other interpolation methods support nonscalar signals."
