hyperbolic cosine of a

Computes element-wise hyperbolic cosine of a tensor.

Parameters:

aTensorLike: Input tensor

Returns:

TensorVariable: Output tensor with the hyperbolic cosine of each element

Notes

This function corresponds to NumPy’s np.cosh function. The hyperbolic cosine is defined as: cosh(x) = (exp(x) + exp(-x))/2

Examples

>>> import pytensor
>>> import pytensor.tensor as pt
>>> x = pt.vector("x")
>>> f = pytensor.function([x], pt.cosh(x))
>>> f([0, 1, 2])
