tanh

Hyperbolic tangent

Syntax

Y = tanh(X)

Description

example

Y = tanh(X) returns the hyperbolic tangent of the elements of X. The tanh function operates element-wise on arrays. The function accepts both real and complex inputs. All angles are in radians.

Examples

collapse all

Create a vector and calculate the hyperbolic tangent of each value.

X = [0 pi 2*pi 3*pi];
Y = tanh(X)
Y = 1×4

         0    0.9963    1.0000    1.0000

Plot the hyperbolic tangent function over the domain .

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

Input Arguments

collapse all

Input angles in radians, specified as a scalar, vector, matrix, or multidimensional array.

Data Types: single | double
Complex Number Support: Yes

Hyperbolic Tangent

The hyperbolic tangent of an angle x is the ratio of the hyperbolic sine and hyperbolic cosine

tanh(x)=sinh(x)cosh(x)=e2x1e2x+1.

In terms of the traditional tangent function with a complex argument, the identity is

tanh(x)=itan(ix).
