While Matlab may not be as fast as C, there are ways to bring it closer. Disclaimer This is not a beginner's tutorial to Matlab, but a tutorial on performance. The methods discussed here are generally fast, but no claim is made on what is fastest. Use at your own risk. Before beginning our main topic, let's step back for a moment and ask ourselves what we really want. Do we want the fastest possible code?|if so, we should switch to a performance language like C. Probably more accurately, we want to spend less time total from developing, debugging, running, and until nally obtaining results. This section gives some tips on working smart, not hard. ...展开收缩
