Details:

Please load ismember_bug.mat attached

A is a scalar double of value 0.
s is a column vector of 299 double values containing at least one 0.
However, ismember failed to recognize the membership of A in s.


load("ismember_bug.mat");
disp(any(s == A));  # Displays 1
disp(ismember(A, s));  # Displays 0, hence a bug
