extended_math library
Library that add functionality of all maths sections that don't
exist in dart:math
At the moment library have 4 sections:
1. General mathematics
2. Complex analysis
3. Discrete mathematics
4. Applied mathematics
Each section don't have full implementation yet. See dartdoc for which functionality are implemented.
Sections are created according to Mathematics Subject Classification.

 ShapeOfProbabilityDistribution

Shape of a probability distribution arises in questions of finding
an appropriate distribution to use to model the statistical properties
of a population, given a sample from that population. The shape of
a distribution may be considered either descriptively, using terms
such as
Jshaped
, or numerically, using quantitative measures such as skewness and kurtosis.  SquareMatrix

 Tensor3
 Class for work with 3 dimensional tensor
 Tensor4
 Class for work with 4 dimensional tensor
 TensorBase
 Base class for tensors
 UniformDistribution
 Class that represent methods of continuous uniform distribution
 Vector
 Class for work with vectors
