erfc - The complementary error function.

Calling Sequence

y = erfc(x)

Parameters

• x : real vector or matrix
• y : real vector or matrix (of same size than x)

Description

erfc computes the complementary error function:

                   /+oo    2
            2      |     -t
     y = -------   |    e    dt
         sqrt(pi)  |
                   /x

     y = 1 - erf(x)
   

Examples

erf([0.5,0.2])+erfc([0.5,0.2])
