Inverse hyperbolic tangent

## Matlab/Scilab equivalent

Matlab | Scilab

    atanh

    atanh

## Particular cases

In y=atanh(x), for real elements of x outside the domain [-1,1], the complex part of Scilab y value is the opposite of Matlab y value.

## Examples

Matlab | Scilab

    y = atanh(2)
    y = 0.5493 + 1.5708i

    y = atanh(2)
    y = 0.5493061 - 1.5707963i
