Description
The
ErfcInv
function computes the inverse complimentary error function values for elements of the input vector a
and writes them to the output vector y
.The inverse complementary error function is defined as given by:
where
erf(x)
denotes the error function and erfinv(x)
denotes the inverse error function. See also Figure
