Follow-up Comment #3, bug #55134 (project octave):

Thanks for the fast response.

The result of running new_tst_fplot.m in MATLAB is the following warning and
the two figures which are drawn correctly.

For K=0: x=-0.247, y=-1.029, z=2.294
Warning: Function behaves unexpectedly on array inputs. To improve
performance, properly vectorize your function to return an output with
the same size and shape as the input arguments.
