QuantLib implements an object library in support of quantitative finance. The Reposit application parses the QuantLib code and generates an application layer called QuantLibAddin which enables QuantLib objects to be stored in an object repository. This facilitates deployment of QuantLib functionality to end user platforms such as spreadsheets. We at Reposit Ltd are experts in QuantLib and can help you with professional support and enhancements. An example of a recent QuantLib project that we have implemented was an enhancement to calculate the exercise probability of Bermudan Swaptions.


reposit implements an object repository in which objects may be created, interrogated, updated, and destroyed. The repository facilitates deployment of object oriented libraries to procedural platforms such as spreadsheets. The project also provides a utility to scan the header files of your C++ library and automatically generate reposit-enabled addins for C++ and Excel. This makes it easy to export your object library to Excel, and to export/import data to/from Excel and C++.
