mg_asinh.pro (mglib)
Inverse hyperbolic sine. Uses the formula:
$$\text{asinh}(z) = \ln(z + \sqrt{1 + z^2})$$
Syntax
result = mg_asinh(z)
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 = 10. * findgen(1000) / 999. - 5.
IDL> plot, x, mg_asinh(x), xstyle=1
This should look like:
