MATLAB: Is there unknown error in strcmp

Question

Hi,

I tried to use strcmp between a string and a cell array. Instead of getting '1', I keep getting '0'. May I know where I go wrong?

Example:

D=[[28];[28];[28]…[0];[0]]

Command Window

>>strcmp('[28]',D(2));

ans = 0

Answer 1

D={[28];[28];[28];[0];[0]};
strcmp('[28]',['[',num2str(D{2}),']'])

or

isequal({28},D(2))

or

28 == D{2}

or

abs(28 - D{2}) < eps(100)
