Inverse Hyperbolic Tangent Function

Syntax	y = atanh(x)
See Also	tanh , asinh , acosh

Description
Returns the element-by-element inverse hyperbolic tangent of x, where x is a real or double-precision matrix. For each (i,j) that is a valid index for x, the corresponding element of x satisfies
     -1 <   x    < 1
             i,j

Example
If you enter
     atanh(tanh([-2., 0., 1.])
O-Matrix will reply
     [ -2 , 0 , 1 ]
