C++ Memory Efficient Solution for Ax=b Linear Algebra System http://stackoverflow.com/questions/1242190/c-memory-efficient-solution-for-ax-b-linear-algebra-system Don't use Boost's LAPACK bindings these were designed for dense matrices not sparse matrices use UMFPACK instead. Long answer..
Does performance differs between Python or C++ coding of OpenCV? http://stackoverflow.com/questions/13432800/does-performance-differs-between-python-or-c-coding-of-opencv implementation is shorter but running time will be more dense and slow compared to the native C implementations. Is there..
How Switch case Statement Implemented or works internally? http://stackoverflow.com/questions/14067547/how-switch-case-statement-implemented-or-works-internally is that when it's suitable that is relatively dense cases a jump table is used. That would mean that something like..
