Absolute value and string to numeric conversion.

  ABS(X) is the absolute value of the elements of X. When

  X is complex, ABS(X) is the complex modulus (magnitude) of

  the elements of X.

  ABS(S), where S is a MATLAB string variable, returns the

  numeric values of the ASCII characters in the string.

  It does not change the internal representation, only the 

  way it prints.
