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.
