Ipopt::StdSchurData::StdSchurData | ( | ) |
This class is the standard implementation of the SchurData interface.
It uses std::vectors to save the data in lists and is build with the goals of understandability, changeability and flexibility in mind rather than performance. Use this class only for academic purposes. If you can exploit a special structure in your SchurData (e.g. all indices are ones), please do in a different implementation of the SchurData interface.
