mxnet.np.cos¶
-
cos
(x, out=None, **kwargs)¶ Cosine, element-wise.
- Parameters
x (ndarray or scalar) – Angle, in radians (\(2 \pi\) rad equals 360 degrees).
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 cosine 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.cos(np.array([0, np.pi/2, np.pi])) array([ 1.000000e+00, -4.371139e-08, -1.000000e+00]) >>> # Example of providing the optional output parameter >>> out1 = np.array([0], dtype='f') >>> out2 = np.cos(np.array([0.1]), out1) >>> out2 is out1 True
