Follow-up Comment #12:

I can confirm that the results with Matlab R2016a differs from Octave 5.1.

I used the attached script to write the resulting matrices to files in Matlab
and Octave (also attached).
Looking at e.g. the bi matrices, the deviations seem to be largest between the
original grid (e.g. at xi = 7.5 and yi = 10.5).

(file #48051, file #48052, file #48053)
