Details:

In Matlab str2num and most other conversion functions return the value and a
flag if the conversion was ok, Octave does not.

Example in Matlab:

>> s = '123';
>> [n, ok] = str2num(s)

n =

   123


ok =

     1

In Octave this error occurs:

"error: element number 2 undefined in return list"
