[Octave-bug-tracker] [bug #35157] Naive users baffled by "complex scalar type invalid as index value"

[Rik]

Follow-up Comment #13, bug #35157 (project octave):

One thing to remember is that it is the typeinfo of the index expression which
is being checked, not the actual characters 'i' or 'e'.  For example:


a = [1:3];
idx = i;
a(idx)

error: complex scalar type invalid as index value


I agree with Jordi that it is useful to know why the index expression is
failing.  In some cases the expression may be very complex (pun intended) and
it would be useful in debugging to have this extra information.

As for the problem with 'doc XXX', I fixed that in this changeset on the
stable branch (http://hg.savannah.gnu.org/hgweb/octave/rev/8a2dc08886ea)
