**pdflib**,
a Python code which
evaluates Probability Density Functions (PDF)
and produces random samples from them,
including beta, binomial, chi, exponential, gamma, inverse chi,
inverse gamma, multinomial, normal, scaled inverse chi, and uniform.

**pdflib** is available in
a C version and
a C++ version and
a FORTRAN90 version and
a MATLAB version and
a Python version.
