How to create 2D plane from Inplane, Crossplane, and Diagonal profiles

I need to create 'A', a 2D plane. size(A)=[512 512]

I have the following:

InplaneA is a column of data, that should occupy Column 256 in A. CrossplaneA=InplaneA but should occupy Row 256 in A. DiagA is a vector that should occupy diagonal of A.

size(InplaneA)=size(CrossplaneA)=size(DiagA)=[512 1]

The rest of the points in matrix A should be the interpolated values from the available data.

How do I achieve that?

You could use something like INPAINT_NANS, but you would be filling the majority of the image based on very little data. I can't imagine how you could ever get meaningfully results based on such little input.
