Is there unknown error in strcmp?

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

[Andrei Bobrov]

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)

Thanks alot, I used the 1st solution.

The 1st solution is really strange. Please note that: D = {[28]} is equivalent to D={28}, which means that you store a scalar double with value 28. Surrounding a scalar by square brackets wastes time and reduses the readability only. STRCMP() operates on strings, which are CHAR vectors.

Finally I suggest to use the 3rd method D{2} == 28, because converting the value to a string is very indirekt and inefficient.

Okay, thanks alot!
