like VectorWithOffset, but with changes in various numeric operators
Compared to VectorWithOffset, the numeric operators +,-,*,/ with NumericVectorWithOffset objects return an object with the largest index range of its arguments. Similarly operators +=,-=,*=,/= potentially grow the *this
object.
In addition, operators +=,-=,*=,/= with objects of type elemT
are defined.

noexcept |
move constructor
implementation uses the copy-and-swap idiom, see e.g. https://stackoverflow.com/a/3279550
|
inline |
adding elements of v
to the current vector
This will grow the vector automatically if the 2nd argument has smaller min_index and/or larger max_index. New elements are first initialised with T() before adding.

subtracting elements of v
from the current vector
See operator+= (const NumericVectorWithOffset&) for growing behaviour

multiplying elements of the current vector with elements of v
