Vector objects are one-dimensional specializations (e.g., more convenient and efficient indexing) of the general Array class. You might also want to look at the Array documentation to see inherited functionality.
Generally the member functions of Array are also available in Vector versions which take an integer where the array needs an IPosition. Since the Vector is one-dimensional, the IPositions are overkill, although you may use those versions if you want to.
Vector<Int> vi(100);
vi.resize(50);
Slices may be taken with the Slice class. To take a slice, one "indexes" with Slice(start, length, inc) where end and inc are optional.
Vector<Float> vf(100);
vf(Slice(0,50,2)) = vf(Slice(1,50,2));
Vector<Float> firstHalf, secondHalf;
firstHalf.reference(vf(Slice(0,50)));
secondHalf.reference(vf(Slice(50,50)));
Element-by-element arithmetic and logical operations are available (in aips/ArrayMath.h and aips/ArrayLogical.h) as well as dot and cross products (in aips/MatrixMath.h).
A Vector can be constructed from an STL vector
. The reverse operation (Array::tovector()
) can construct an STL vector
from any Array.
Tip: To create any other STL container from an Array (or the reverse), always create from/to a vector
, and use the range constructor to create from/to others (like set, list, deque);
As with the Arrays, if the preprocessor symbol AIPS_DEBUG is defined at compile time invariants will be checked on entry to most member functions. Additionally, if AIPS_ARRAY_INDEX_CHECK is defined index operations will be bounds-checked. Neither of these should be defined for production code.
