Details:
When I try to redirect a function evaluation with an "ans" output, it appears
to get lost for Octave (but not MATLAB). Here is an illustration:
% bar.m
function v = bar()
v = 42;
end
% baz.m
function varargout = baz()
for i=1:max(1,nargout) % always ans
varargout{i} = 42;
end
end
% foo.m
function varargout = foo(c)
if c
[varargout{1:nargout}] = bar();
else
[varargout{1:nargout}] = baz();
end
end
Test script with results for MATLAB and Octave
% test_foo.m
bar % ans=42 in both MATLAB and Octave
baz % ans=42 in both MATLAB and Octave
a = foo(true);
foo(true);
foo(true) % ans=42 in MATLAB, nothing in Octave
a = foo(false);
foo(false);
foo(false) % ans=42 in MATLAB, nothing in Octave
[a,b] = foo(false);
