Computes the complimentary error function for real arguments. The erfc function takes only a single argument
y = erfc(x)
where x is either a float or double array. The output vector y is the same size (and type) as x.
The erfc function is defined by the integral:
and is the integral of the normal distribution.
Here is a plot of the erfc function over the range [-5,5].
--> x = linspace(-5,5);
--> y = erfc(x);
--> plot(x,y); xlabel('x'); ylabel('erfc(x)');
which results in the following plot.
