[Octave-patch-tracker] [patch #8872] add isocaps

[Philip Nienhuis]

Follow-up Comment #16, patch #8872 (project octave):

The demo doesn't work.
Stepping manually through the demo in debug mode:

:
>> isonormals (x, y, z, val, p_iso)

>> fvc_xmin = isocaps (x, y, z, val, iso, "xmin", "b")

It seems the "verbose" argument hasn't been initialized in isocaps.m or its
subfunctions.
