pymc.math.cos#
- pymc.math.cos = Elemwise(scalar_op=cos,inplace_pattern=<frozendict {}>)[source]#
cosine of a
Computes element-wise cosine of a tensor in radians.
- Parameters:
- a
TensorLike
Input tensor in radians
- a
- Returns:
TensorVariable
Output tensor with the cosine of each element
Notes
This function corresponds to NumPy’s np.cos function.
Examples
>>> import pytensor >>> import pytensor.tensor as pt >>> import numpy as np >>> x = pt.vector("x") >>> f = pytensor.function([x], pt.cos(x)) >>> f([0, np.pi / 2, np.pi]) array([ 1.000000e+00, 6.123234e-17, -1.000000e+00])
