tensor.ravel_index

    fn ravel_index(self: @Tensor<T>, indices: Span<usize>) -> usize;

Converts a multi-dimensional index to a one-dimensional index.

Args

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

• indices(Span<usize>) - The indices of the Tensor to ravel.

Panics

• Panics if the indices are out of bounds of the Tensor shape.

Returns

The index corresponding to the given indices.

Examples

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

use orion::operators::tensor::{TensorTrait, Tensor, U32Tensor};

fn ravel_index_example() -> usize {
    let tensor = TensorTrait::<u32>::new(
        shape: array![2, 2, 2].span(), data: array![0, 1, 2, 3, 4, 5, 6, 7].span(),
    );

    // We can call `ravel_index` function as follows.
    return tensor.ravel_index(indices: array![1, 3, 0].span());
}
>>> 10 
// This means that the value of indices [1,3,0] 
// of a multidimensional array can be found at index 10 of Tensor.data.
