Function: atanh
Description: atanh returns the hiperbolic arc tangent of the elements of an array.
Usage: z = atanh(x)
Input:
x d1 x d2 x ... x dn array
Output:
z d1 x d2 x ... x dn array
Notes:
the absolute value of the input values must be < 1. otherwise NaN's are returned.
Example:
x = #(0, 1/2)~#(1/3, 1/4) 
atanh(x)
Result:
[1,]     0 0.34657 
[2,] 0.54931 0.25541
