   I have a fitting problem, that is to solve system of equations
   whose parameters are in a range,i.e are under uncertainties.And I
   want to get a result including centre value and its uncertainty
   for each variables.
   Thanks!

Hi,
IN ROOT we have a specific class for solving system of equations, see
https://root.cern/doc/master/classROOT_1_1Math_1_1GSLMultiRootFinder.html

Otherwise you can often re-formulate your problem as a minimization one and in this case you can
use any minimizer algorithm available in ROOT such as Minuit
