How to use assert_abs_diff_eq with an arr2?

Sorry I am terrible at formatting markdown so I pasted a picture of the code as well.
I have a test that I want to use to check some 2D array maths. I want to do an assert on an approximately equal value. The last line does not work as the trait is not implemented.

#[test]
fn test_create_y_rotation_matrix() {
let expected = arr2(&[
[0.93969262, 0., 0.34202015, 0.],
[0., 1., 0., 0.],
[-0.34202015, 0., 0.93969262, 0.],
[0., 0., 0., 1.],
]);

let result = Create_Y_Rotation_Matrix(20.);

assert_abs_diff_eq!(expected, result);                                                                                            

}

Your inline type hints suggest one array has elements of f64 and the other f32, otherwise they should be the same type. I'd check aligning them on type first.

Thanks, I forced to f32 for both but it still gives the same error
