.SH NAME
erfc -  The complementary error function.
.SH CALING SEQUENCE
.nf
 y = erfc(x)
.fi
.SH PARAMETERS
.TP
x
: real vector
.TP
y
: real vector (of same size)
.SH DESCRIPTION
 \fVerfc\fR computes the complementary error function:
.IG
.nf
                      /inf
     y = 2/sqrt(pi) *|  exp(-t^2) dt
                     /x
     y= 1 - erf(x)
.fi
.FI
.LA $$ y = 2/\sqrt(\pi) \int_x^{\infty} exp(-t^2)dt $$
.LA $$ y = 1-erf(x) $$
.SH EXAMPLE
.nf
erf([0.5,0.2])+erfc([0.5,0.2])
.fi
