NumPy - tanh() function
The NumPy tanh() function is used to calculate hyperbolic tangent of a value. The hyperbolic tangent of x is defined as:
where e is an Euler's number.
Syntax
numpy.tanh(a, out=None)
Parameters
a |
Required. Specify array (array_like) containing elements, of which the hyperbolic tangent is calculated. |
out |
Optional. Specify a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. |
Return Value
Returns the hyperbolic tangent of each element in a.
Example:
In the example below, numpy tanh() function is used to calculate the hyperbolic tangent of each element present in array Arr.
import numpy as np
Arr = np.array([1, 2, 3, 4])
print("The hyperbolic tangent of values:")
print(np.tanh(Arr))
The output of the above code will be:
The hyperbolic tangent of values: [ 0.76159416 0.96402758 0.99505475 0.9993293 ]
