You could also call the Java GUI from an Octave function or script (from
within Octave).

No, there is no way that I know of to interpret and execute an Octave
function without the Octave interpreter.

If it were possible to compile an Octave function or script into a
standalone program, it would still contain the entire Octave interpreter
embedded within it, so I don't see how that is practically different
from installing Octave.

(The hospital should be more concerned with Java being installed, but
that's their choice.)

If installing Octave is absolutely impossible, then you will need to
rewrite the algorithm into Java or some other language that is allowed
by your system constraints.
