mars.tensor.radians#

mars.tensor.radians(x, out=None, where=None, **kwargs)[source]#

Convert angles from degrees to radians.

Parameters

  • x (array_like) – Input tensor in degrees.

  • out (Tensor, None, or tuple of Tensor and None, optional) – 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 tensor is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

  • where (array_like, optional) – Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.

  • **kwargs –

Returns

y – The corresponding radian values.

Return type

Tensor

Examples

Convert a degree array to radians

>>> import mars.tensor as mt

>>> deg = mt.arange(12.) * 30.
>>> mt.radians(deg).execute()
array([ 0.        ,  0.52359878,  1.04719755,  1.57079633,  2.0943951 ,
        2.61799388,  3.14159265,  3.66519143,  4.1887902 ,  4.71238898,
        5.23598776,  5.75958653])

>>> out = mt.zeros((deg.shape))
>>> ret = mt.radians(deg, out)
>>> ret is out
True
