Constructors and destructor | |
| These do not have an exact analogue in C++. The user does not need to know structure of Clp_Simplex.
For all functions outside this group there is an exact C++ analogue created by taking the first parameter out, removing the Clp_ from name and applying the method to an object of type ClpSimplex. | |
