rg

Random Distribution Generator (Python C API Extension)

Generates random numbers coming from the distributions:

  • Uniform(a,b,N)
  • Bernoulli(N)
  • Binomial(n,p,N)
  • NegativeBinomial(k,p,N)
  • Geometric(p,N)
  • Poisson(mean,N)

where N is the number of numbers generated.

Usage Example:

import rg

for i in rg.Poisson(4.5,N=10000):
  print(i)

MacOS

Compiling and linking:

g++ -DDISTRIBUTIONS_COMPAT_C -fpermissive -c distributions.cpp
gcc -DNDEBUG -g -O3 -Wall -fPIC -I/$INCLUDE_DIR -c rgmodule.c
gcc -bundle -undefined dynamic_lookup rgmodule.o distributions.o -lstdc++ -L/LIB_DIR -o rg.so
  • with $INCLUDE_DIR - directory where are the include files, including Python.h;
  • with $LIB_DIR - library directory
  • import module in the directory where is rg.so
