%% Avoid Roundoff Errors Using Complementary Error Function % You can use the complementary error function |erfc| in place of % |1 - erf(x)| to avoid roundoff errors when |erf(x)| is close to |1|. % % Show how to avoid roundoff errors by calculating |1 - erf(10)| using |erfc(10)|. % The original calculation returns |0| while |erfc(10)| returns the % correct result. % Copyright 2015 The MathWorks, Inc. 1 - erf(10) erfc(10)
