hyperbolic arc sine of a

Computes element-wise inverse hyperbolic sine of a tensor.

Parameters:

aTensorLike: Input tensor

Returns:

TensorVariable: Output tensor with the hyperbolic arc sine of each element

Notes

This function corresponds to NumPy’s np.arcsinh function. The inverse hyperbolic sine is defined for all real numbers.

Examples

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