return

Purpose

Return to the invoking function.

return

return causes a normal return to the invoking function or to the keyboard.

If the determinant function were an M-file, it might use a return statement in handling the special case of an empty matrix as follows:

function d = det(A)
%DET det(A) is the determinant of A.
if isempty(A)
    d = 1;
    return
else
    ...
end
