previous discussion of these problems: https://news.ycombinator.com/item?id=30895307 https://news.ycombinator.com/item?id=30895307 > The real problem is the Numerical Recipes license, which is extremely restrictive - probably more so than most users realize. I won't dignify it with a link, but you can find licensing terms on their website. NR routines are copyrighted (fine) and cannot be redistributed as source (annoying but not uncommon for COMMERCIAL software, somewhat unusual for scientific software). There is no exception for noncommercial or scientific use, which is Grinchy and irritating, especially given that two of the authors acknowledge funding from the NSF for work on numerical methods. Beyond that, the single-CPU/single-screen terms of their license are almost impossible for a working scientist to comply with, especially in a networked environment.
