Re: find, then store functions into array problem

in reply to find, then store functions into array problem

To extract the strings that are not + or -,

my @remaining = grep {defined} split /[+-]{2,}/, $righteq;
  # fixed 2nd arg error

I assume you don't mean for these functions to be in perl, since your ^ appears to be exponentiation.

A more detailed regex for your special case can be constructed. Left as an exercise for the reader.

Update: Ok, using your regex:

my @remaining = grep {defined}
                      split /
                            (e\^\(t\+-(\d+\.?\d*|\.\d+)\))
                                   # the special, captured
                            |      # or else
                            [+-]+  # filler, not captured
                            /x,
                            $righteq;
