result = mg_atanh(z)
Inverse hyperbolic tangent. Uses the formula:
$$\text{atanh}(z) = \frac{\ln(\frac{1 + z}{1 - z})}{2}$$
Return value
float, double, complex, or double complex depending on the input
Parameters
- z in required type=numeric
input
Examples
The arc hyperbolic sine function looks like:
IDL> x = 2. * findgen(1000) / 999. - 1.
IDL> plot, x, mg_atanh(x), xstyle=1
