The Log Normal Probability Density Function

**LOG_NORMAL**,
a C++ library which
can evaluate quantities associated with the log normal Probability
Density Function (PDF).

If X is a variable drawn from the log normal distribution, then correspondingly, the logarithm of X will have the normal distribution.

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

LOG_NORMAL_TRUNCATED_AB, a C++ library which returns quantities associated with the log normal Probability Distribution Function (PDF) truncated to the interval [A,B].

NORMAL, a C++ library which samples the normal distribution.

TRUNCATED_NORMAL, a C++ library which works with the truncated normal distribution over [A,B], or [A,+oo) or (-oo,B], returning the probability density function (PDF), the cumulative density function (CDF), the inverse CDF, the mean, the variance, and sample values.

UNIFORM, a C++ library which samples the uniform distribution.
