Follow-up Comment #5, bug #55667 (project octave):

Philip, if you are asking is something like

y = x(2:4)(2);

automatically transformed to x(3), then the answer is no.  It is just
performed as a series of indexing calls that generate internal temporary
variables.  So ultimately it's not much different from writing

tmp = x(2:4);
y = tmp(2);

except that in the first case, the internal temporary is not entered into the
symbol table and may be cleared as soon as it is no longer needed.

But Octave also attempts to manage data array slices without making copies, so
indexing like this should not create additional copies of the original array.
