bracematch

  BRACEMATCH - Match parenthesis in a text string

   [POS_MATCH,BRACEDEPTH] = BRACEMATCH(STR, POS)

   Finds the right parenthesis ')' that matches the left paranthesis
   '(' in string STR at position POS.

   One can modify the behavior of this function by passing name/value pairs:
   Name (default):               | Description
   ---------------------------------------------------------------------
   braceleft ('(')               | The character to be the left parenthesis
                                 |   (other examples, '[', '{', '<')
   braceright (')')              | The character to be the right parenthesis
                                 |   (other examples, ']', '}', '>')
   bracedepth ([])               | To save time, if one has computed the
                                 |   brace level using the function BRACELEVEL,
                                 |   one can pass it here. If empty, the
                                 |   brace level will be recalculated.
   Examples:
      str = 'this is (a test of (depth))';
      match1=bracematch(str, 9)
      match2=bracematch(str,20)
