_______________________________________________________
Details:
With the patch from bug #42408 (revision 18785:1f170b211be3) the following
regression has been introduced: When x is an object whose class overrides the
size function and x's size is not [1 1] then isequal (x, x) == false.
E.g.:
octave:1> pkg load interval
octave:2> x = infsup (magic (3));
octave:3> isequal (x, x)
ans = 0
The reason is, that the new code uses cellfun for checking sizes:
t = all (size (x,k) == cellfun ("size", varargin, k));
cellfun ("size", …) evaluates the built-in size function and not the
overriden size function from the class. Thus, t will eventually be false if
size (x, k) ~= 1 for any k.
Proposed fix: Use cellfun (@size, …) instead of cellfun ("size", …)
