There's probably a better way, but try this at the command line in
Octave ('ismember' is an octave-forge function):


Octave:1> ['ab1234567890cd'](find(ismember(toascii('ab1234567890cd'),[48:57])) )


([48:57]) are the ascii integers that correspond to the strings
['0':'9'], in case you were wondering)
