[1X4 Implementation[0X The [5Xlinboxing[0m package consists three parts. The first part is written in [5XGAP[0m, and this consists of test routines and wrappers for functions in the [5Xlinboxing[0m kernel module. The second part is the kernel module's interface to [5XGAP[0m, which is written in C. This handles the interface between [5XGAP[0m and the third part, which is the C++ code which calls functions in the LinBox library. In the C++ part of the kernel module, the [5XGAP[0m objects such as vectors, matrices and their elements are converted into the corresponding LinBox data types. The requested LinBox function is then called, and the result converted back onto [5XGAP[0m objects. Currently, all [5XGAP[0m matrices are converted into dense matrices in the LinBox library. LinBox provides good support for sparse matrices, but at present there is no standard way in [5XGAP[0m to represent sparse matrices. There are plans to overhaul matrix objects in [5XGAP[0m, and once sparse matrix objects are provided in [5XGAP[0m, these should be converted into LinBox sparse matrices. For more details of the implementation, please refer to the source code documentation. The C and C++ source code can be found in the [11Xsrc[0m directory of the [5Xlinboxing[0m package, and contains comments which can be converted into HTML documentation using [11Xdoxygen[0m (which must therefore be available on your system).
