- brainpy.math.tanh(x)[source]#
Compute hyperbolic tangent element-wise.
LAX-backend implementation of
numpy.tanh().Original docstring below.
Equivalent to
np.sinh(x)/np.cosh(x)or-1j * np.tan(1j*x).- Parameters
x (array_like) – Input array.
- Returns
y – The corresponding hyperbolic tangent values. This is a scalar if x is a scalar.
- Return type
ndarray
