Function response_exp_map 

pub fn response_exp_map(
    manifold: ResponseManifold,
    tangent: ArrayView2<'_, f64>,
    base: ArrayView1<'_, f64>,
) -> Result<Array2<f64>, String>

Batched response-geometry exponential: map predicted tangent coordinates back to manifold-valued responses at base. Inverse of response_log_map with the same shapes.
