[Octave-bug-tracker] [bug #54698] Precedence of call/indexing operator over transpose operator

[anonymous]

Follow-up Comment #13, bug #54698 (project octave):

I think here is my final suggestion.

Three new operators will be introduced in the documentation:


{t/c...}()
{t/c...}{}
{t/c...}.


Where {t/c...} means consecutive number of transpose/ctranspose operators, and
those three operators take the same level of precedence as of the call
operator. For example in the expression:


A'.'.'(X)


the consecutive number of transpose/ctranspose operators followed by a call
operator are regarded as one operator and it behaves as :


temp = A';
temp = temp.';
temp = temp.';
temp(X)


Also as a bug is reported in comment8
<https://savannah.gnu.org/bugs/index.php?54698#comment8>, I think the postfix
increment/decrement operators should have the same level of precedence as of
the call operator.

Therefor the table of precedence will be changed to :


‘()’ ‘{}’ ‘.’ ‘{t/c...}()’ ‘{t/c...}{}’ ‘{t/c...}.’
‘++’ ‘--’

‘'’ ‘.'’ ‘^’ ‘**’ ‘.^’ ‘.**’


Thanks to all.
