The SetCorrelation( obj1, obj2, cc ) command sets a correlation coefficient cc between the quantities-with-error obj1 and obj2 for the current session.

To set a correlation for all future Maple sessions, add the SetCorrelation command to your Maple initialization file. For more information, see Create Maple Initialization File .

The correlation cc must be in the range $\mathrm{-1}..1$.

The quantities-with-error obj1 and obj2 must be distinct.

Neither of the quantities-with-error obj1 and obj2 can have functional dependence on other quantities-with-error.
