Function index

Indexes the `input` Array using `seqs` Sequences # Examples ```rust use arrayfire::{Dim4, Seq, index, randu, print}; let dims = Dim4::new(&[5, 5, 1, 1]); let a = randu:: (dims); let seqs = &[Seq::new(1.0, 3.0, 1.0), Seq::default()]; let sub = index(&a, seqs); println!("a(seq(1, 3, 1), span)"); print(&sub); ```

(input: &Array<IO>, seqs: &[Seq<T>])

/// print(&sub);
/// ```
pub fn index<IO, T>(input: &Array<IO>, seqs: &[Seq<T>]) -> Array<IO>
where
    c_double: From<T>,
    IO: HasAfEnum,
    T: Copy + HasAfEnum + IndexableType,
{
    let seqs: Vec<SeqInternal> = seqs.iter().map(|s| SeqInternal::from_seq(s)).collect();
    unsafe {
        let mut temp: af_array = std::ptr::null_mut();
        let err_val = af_index(
            &mut temp as *mut af_array,
            input.get(),
            seqs.len() as u32,
            seqs.as_ptr() as *const SeqInternal,
        );
        HANDLE_ERROR(AfError::from(err_val));
        temp.into()
    }
}
