mxnet.np.sinh

sinh(x, out=None, **kwargs)

Hyperbolic sine, element-wise. Equivalent to 1/2 * (np.exp(x) - np.exp(-x)) or -1j * np.sin(1j*x).

Parameters
  • x (ndarray or scalar) – Input array or scalar.

  • out (ndarray or None) – 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. The dtype of the output is the same as that of the input if the input is an ndarray.

Returns

y – The corresponding hyperbolic sine values. This is a scalar if x is a scalar.

Return type

ndarray or scalar

Notes

This function only supports input type of float.

Examples

>>> np.sinh(0)
0.0
>>> # Example of providing the optional output parameter
>>> out1 = np.array([0], dtype='f')
>>> out2 = np.sinh(np.array([0.1]), out1)
>>> out2 is out1
True
