Expand description

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

@param highs A pointer to the Highs instance. @param has_primal_ray A pointer to an int to store 1 if the primal ray exists. @param primal_ray_value An array of length [num_col] filled with the unbounded ray.

@returns A kHighsStatus constant indicating whether the call succeeded.
