MATLAB: How to use regexp for negative and positive integers

positive

hello,
I have a trouble using regexp. I read a sensor value that can contain negative or positive integers and I need both. but until now I only get one of it(only positive integers o negative integers). here is my code that only reads positive integers:
FSR1 = regexp(FSR1,'\d+(\.)?(\d+)?','match');
and these are some types of integers that I`m reading:
 '204'
    '203'
    '191'
    '133'
    '63'
    '-28'
    '-109'
    '-145'
    '-196'
    '-134'
can someone help me, please?

Best Answer

   a = {'204'
      '203'
      '191'
      '133'
      '63'
      '-28'
      '-109'
      '-145'
      '-196'
      '-134'}
FSR1 = str2double(regexp(a,'[-]?\d+(\.)?(\d+)?','match','once'))
