Foam::interpolationTable
Description
A list of times and values.
The time values must be positive and monotonically increasing.
An interpolation/look-up table of scalar vs <Type> values.
The reference scalar values must be positive and monotonically increasing.
The handling of out-of-bounds values depends on the current setting
of @a outOfBounds.

Description
A library of runtime-selectable pdf's.
A library of runtime-selectable PDF's.
Returns a sampled value given the expectation (nu) and variance (sigma^2)
Sample of planned pdfs (beta p. 374-375):
- binomial
- geometric
- Poisson
- hypergeometric
- Pascal
- uniform
Current PDF's include:
- exponential
- fixedValue
- general
- multi-normal
- normal
- Gamma
- chi
- t?
- F?
- beta
- Weibull
- Rayleigh
- Cauchy?
- Rosin-Rammler
- uniform
The pdf is tabulated in equidistant nPoints, in an interval.
These values are integrated to obtain the cumulated pdf,
These values are integrated to obtain the cumulated PDF,
which is then used to change the distribution from unifrom to
the actual pdf.
