Sometimes you need a little code to do some scientific computing and you don’t want to take on a dependence to a huge and possibly unfamiliar library. This page is an index to code snippets in multiple languages that solve that problem.
The software listed here has been designed to minimize dependencies, minimize complexity, and maximize transparency. That sometimes means sacrificing efficiency.
All code here is under BSD license. Do whatever you want with it. Use at your own risk.

Random number generation
Inverse gamma: C++
Log normal: C++
C++ TR1 has code for generating random samples from normal, exponential, gamma, and Poisson distributions directly. Random number generation using C++ TR1 explains how to use this built-in functionality and now to bootstrap the built-in functions to generate samples from Cauchy, Student-t, Snedecor-F, and Weibull distributions.
