function indices = ppp_indices (names,sympar,sympars)

  ## usage:  indices = ppp_indices (names,sympar)
  ##
  ## names: column vector of component names
  ## sympar symbolic parameter structure for system
  ## sympars symbolic parameter structure for sensitivity system
 

  ## Returns a matrix indices with 3 columns, one row per name
  ## First  col: index of ith parameter of sensitivity system
  ## Second col: index of ith sensitivity parameter of sensitivity system
  ## Third col : index of ith parameter of system
