Mathworks Computational Finance conference takeaways for quality of Matlab tool box product versus FREE open source R
Here is one person’s view of Matlab’s day of COmputation Finance in NYC. His view is quite different which shows the extensive testing Mathworks put into their products for quality assurance. It seems one may need to question of the R community puts the same amount into their open packages. Just saying if you would be really confident to make trading decisions of it.
Mathworks appears to be doing a decent QA job. I grilled the Development Team during the Dev Q&A session and was satisfied with their answers. They do fault injection testing for out of memory error recovery and other fault conditions.
They use Matlab code to generate an intra-dependencies matrix of the codebase and track all dependencies and cyclomatic complexity. They also use many tools for code coverage analysis.
This is all on top of extensive unit, and functional regression testing.
As a Senior QA Engineer for over decade, this level of QA Testing is rarely seen.
Thanks to this person who sent this and for attending this conference I wanted to go to. Of course being in Toronto, we never see these. Time to consider a move.
