Computes ranging information for the solved LP. The solver must have an optimal LP solution before calling this function.
hi_solver_get_ranging(solver)A list with components:
Logical, whether the ranging data is valid.
Lists with value, objective, in_var, ou_var vectors for cost ranging (length num_col).
Lists for column bound ranging.
Lists for row bound ranging (length num_row).
An object of class "highs_solver".
