How do we store workspace variables identifed using regular expressions.

Consider the following example below...

ex_1 = 5;
ex_2 = 3;
i_i = 4;
%if I do this 
whos -regexp ^ex_[1]*|^i.\d+
  Name      Size            Bytes  Class     Attributes

  ex_1      1x1                 8  double              
  ex_2      1x1                 8  double              
%it works
%but if I do this
s = whos(-regexp ^ex_[1]*|^i.\d+);
Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.
%it throws an error
