residuals
 

Hi, I would like to know the real meaning of the residuals: being them absolute residuals, I' ve got to think that they have to tend to zero when the calculation is going to convergence, or it' s enough that their ratio with the value to which they refer (that is the relative residual) tends to zero ? The problem is that looking at the calculation monitoring information, the residuals written are the absolute ones. Thank you for your help.
