tensor.acosh

    fn acosh(self: @Tensor<T>) -> Tensor<T>;

Computes the inverse hyperbolic cosine of all elements of the input tensor.

$$y_i=acosh({x_i})$$

Args

• self(@Tensor<T>) - The input tensor.

Returns

Returns a new tensor in T with the hyperblic cosine of the elements of the input tensor.

Type Constraints

Constrain input and output types to fixed point tensors.

Examples

use core::array::{ArrayTrait, SpanTrait};

use orion::operators::tensor::{TensorTrait, Tensor, FP8x23Tensor};
use orion::numbers::{FixedTrait, FP8x23};

fn acosh_example() -> Tensor<FP8x23> {
    let tensor = TensorTrait::<FP8x23>::new(
        shape: array![2, 2].span(),
        data: array![
            FixedTrait::new_unscaled(1, false),
            FixedTrait::new_unscaled(2, false),
            FixedTrait::new_unscaled(3, false),
            FixedTrait::new_unscaled(4, false)
        ]
            .span(),
    );
