They are returning the ASCII decimal representations of the respective letters. I cannot find anything in the documentation for the Symbolic Math Toolbox real function or the core MATLAB documentation for real to explain it.

for example, this code:

real z
whos
char(ans)
whos

returns this result:

ans =

     122

    Name         Size            Bytes  Class     Attributes

    ans          1x1                 8  double              

ans =

      'z'

    Name         Size            Bytes  Class     Attributes

    ans          1x1                 2  char

Perhaps one of the MathWorks folks can explain what is going on.
