asinh

Inverse hyperbolic sine

Syntax

Y = asinh(X)

Description

Y = asinh(X) returns the inverse hyperbolic sine for each element of X.

The asinh function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Examples

collapse all

Graph the inverse hyperbolic sine over the domain $-5 \le x \le 5$.

x = -5:.01:5;
plot(x,asinh(x))
grid on
xlabel('x')
ylabel('y')

More About

collapse all

Inverse Hyperbolic Sine

For real values x in the domain of all real numbers, the inverse hyperbolic sine satisfies

sinh1(x)=log(x+x2+1).

For complex numbers z=x+iy, the call asinh(z) returns complex results.

Tall Array Support

This function fully supports tall arrays. For more information, see Tall Arrays.
