Detailed Description

A runtime-sized linear algebra vector of doubles.

This class is the runtime-sized equivalent of apf::Vector. It keeps all values in a single dynamically allocated array. Due to the use of dynamic allocation, users should avoid copying this class as much as possible. To help with this, we provide things like operator+= instead of operator+ to discourage users from creating temporary copies. The code for these methods is still inlined in an effort to keep your linear algebra running as fast as possible.

immutable index operator

note that we do inherit the square-bracket index operator from DynamicArray, but we use parentheses here to be consistent with apf::DynamicMatrix
