atanh

Inverse hyperbolic tangent in radians

Usage

atanh(A)

• A should be an array, which can be complex or real.
• It returns an array containing the inverse hyperbolic tangent (in radians) of each element of A.
• For real elements of A lying in $[-1,1]$​, it returns real values​​. (See example below.)
• For real elements of A with absolute values greater than 1, it returns complex numbers.
• The output has the same size as A.

Example

Input

x=linspace(-1,1);
y=atanh(x);
plot(x,y,'.-');
xlabel('x')
ylabel('atanh(x) in radians')

Output
