TANH Hyperbolic Tangent Function

Section: Mathematical Functions

Usage

Computes the hyperbolic tangent of the argument. The syntax for its use is 
   y = tanh(x)

Function Internals

The tanh function is computed from the formula

Examples

Here is a simple plot of the hyperbolic tangent function 
--> x = linspace(-5,5);
--> plot(x,tanh(x)); grid('on');
