What is the advantage of MtxVec against managed code math libraries?
There are several advantages. Well tested code which did not have to be translated in to a new language possibly introducing new bugs is one. Another advantage is performance, this includes both the direct execution performance and reduced memory usage when solving the same kind of problems. The performance differences is really by “orders of magnitude”. The main aim of MtxVec so to leave .NET developers the productivity, without paying with the performance.
