y = erf(x)
y = erfc(x)
y = erfcx(x)
y = erf(x)
, the error function, is the integral of the Gaussian distribution function from 0
to x
:
y = erfc(x)
returns the value of the complementary error function:
y = erfcx(x)
returns the value of the scaled complementary error function:
For large x
, erfcx(x)
is approximately
