Follow-up Comment #1:

Octave does not yet have support for ui objects. Thus, Octave will not be
able to run your script. However, the error you've encountered is a bug which
has already been fixed in the developers sources.

See the changes for Dec 2010 at the link below.

[bug #31974] Interpreter fails to create complex numbers with Inf complex parts

Please use the bug tracker to post updates to a bug report.  The mailing list is intended as a read-only
notification stream.  Info posted to this mailing list address won't appear in the tracker database where
it is most useful.

Follow-up Comment #17, bug #31974 (project octave):

It is also possible that Matlab changed the behavior of real*complex just to
make this thing work. I would advise to avoid doing such a general (and kinda
stupid) change and only implement the constant folding optimization as
suggested by JWE, i.e. a+b*i  -> complex(a, b) where a, b are scalar
constants, because that's what most people mean. Don't change anything else.
It does mean a sort of inconsistency, but not quite, because we can say that
the expression is simply parsed as a constant.

Please use the bug tracker to post updates to a bug report.  The mailing list is intended as a read-only
notification stream.  Info posted to this mailing list address won't appear in the tracker database where

Follow-up Comment #18, bug #31974 (project octave):

What does Matlab do for

function f (x, y)
  x * y
  x / y
end

f (Inf, i)

If it produces 0+Infi and 0-Infi, then this is not limited to constant
folding, so we have to implement the special case in the operators that might
be affected.  I would guess this includes *, .*, /, ./, , and . for mixed real
and complex cases for scalar by scalar and scalar by array operations for both
double and single values.  Or, we can use a class derived from std::complex
that implements the special cases we want.  Using a derived class like this
would probably require fewer changes to Octave since we already have Complex
and FloatComplex typedefs, but then it would mean that anywhere the class is
used, we get the special behavior, and I'm not sure that's really what we
want.

In any case, I think this change should wait until after 3.4 is released.

Follow-up Comment #1, bug #32033 (project octave):

This looks like Octave is telling you that its fnmatch function is not
available, but I don't see how that could happen.  The fnmatch function is
defined in dirfns.cc, and is always defined as far as I can tell.

What happens if you start Octave and type

  fnmatch ("f*", "foo")

at the command prompt?
