Detailed Description

1-D array used in linear algebra.

This class implements the concept of vector as used in linear algebra. As such, it is not meant to be used as a container - std::vector should be used instead.

Tests:

construction of arrays is checked in a number of cases

Examples

Gaussian1dModels.cpp, and GlobalOptimizer.cpp.
