Computes the inverse hyperbolic tangent of its argument. The general syntax for its use is
y = atanh(x)
where x
is an n
-dimensional array of numerical type.
The atanh
function is computed from the formula
where the log
(and square root) is taken in its most general sense.
Here is a simple plot of the inverse hyperbolic tangent function
--> x = -0.99:.01:0.99; --> plot(x,atanh(x)); grid('on');
