Best Practices for Programming MATLAB

These are the main coding practices and tools I always rely on.

1. Vectorize (but sensibly).
2. Use bsxfun in lieu of repmat where possible.
3. When looping through an array, loop down columns to access memory in the same order that MATLAB stores the data in.
4. Profile the code. I am often surprised about what is taking up the time.
5. Pay attention to messages from the Code Analyzer.
6. Use functions instead of scripts.
7. Don't "poof" variables into any workspaces. Translation, don't use load without a left-hand side; avoid eval, evalin, and assignin.
8. Use logical indexing instead of find.
9. Avoid global variables.
10. Don't use equality checks with floating point values.
