cern.colt.matrix.impl.DenseObjectMatrix1D

Dense 1-d matrix (aka vector) holding Object elements. First see the package summary and javadoc tree view to get the broad picture.

Implementation:

Internally holds one single contigous one-dimensional array. Note that this implementation is not synchronized.

Memory requirements:

memory [bytes] = 8*size(). Thus, a 1000000 matrix uses 8 MB.

Time complexity:

O(1) (i.e. constant time) for the basic operations get, getQuick, set, setQuick and size,
