#tensor.acos

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

Computes the arccosine (inverse of cosine) of all elements of the input tensor.

Args

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

Returns

A new Tensor<T> of the same shape as the input tensor with the arccosine value of all elements in the input tensor.

Type Constraints

Constrain input and output types to fixed point tensors.

Example

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

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

fn acos_example() -> Tensor<FP8x23> {
    let tensor = TensorTrait::<FP8x23>::new(
        shape: array![2].span(),
        data: array![FixedTrait::new_unscaled(0, false), FixedTrait::new_unscaled(1, false),]
            .span(),
    );

    return tensor.acos();
}
