tanh - Hyperbolic tangent

Syntax

Y = tanh(X)

Description

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

Y = tanh(X) returns the hyperbolic tangent of each element of X.

Examples

Graph the hyperbolic tangent function over the domain .

x = -5:0.01:5; 
plot(x,tanh(x)), grid on

Definitions

The hyperbolic tangent can be defined as

Algorithms
