erfcx - scaled complementary error function.

Calling Sequence

y = erfcx(x)

Parameters

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

Description

erfcx computes the scaled complementary error function:

              2                
     y = exp(x ) * erfc(x)

                1
     y  -->  ---------    when x --> +oo
             x sqrt(pi)
