Function highs_sys::Highs_getDualRay

pub unsafe extern "C" fn Highs_getDualRay(
    highs: *const c_void, 
    has_dual_ray: *mut HighsInt, 
    dual_ray_value: *mut f64
) -> HighsInt

Get an unbounded dual ray that is a certificate of primal infeasibility.

@param highs a pointer to the Highs instance @param has_dual_ray a pointer to an int to store 1 if the dual ray exists @param dual_ray_value an array of length [num_row] filled with the unbounded ray

@returns a kHighsStatus constant indicating whether the call succeeded
