Comparing for Equality Using Operators

You can use MATLAB relational operators on character arrays, as long as the arrays you are comparing have equal dimensions, or one is a scalar. For example, you can use the equality operator (==) to determine which characters in two strings match.

• A = 'fate';
  B = 'cake';
  
  A == B
  ans =
      0   1   0   1
  

All of the relational operators (>, >=, <, <=, ==, !=) compare the values of corresponding characters.
