## Uses of Class
cern.colt.matrix.impl.AbstractMatrix1D

Packages that use AbstractMatrix1D
Package | Description
--- | ---
cern.colt.matrix | Matrix interfaces and factories; efficient and flexible dense and sparse 1, 2, 3 and d-dimensional matrices holding objects or primitive data types such as `int`, `double`, etc; Templated, fixed sized (not dynamically resizable); Also known as multi-dimensional arrays or Data Cubes.
cern.colt.matrix.impl | Matrix implementations; You normally need not look at this package, because all concrete classes implement the abstract interfaces of `cern.colt.matrix`, without subsetting or supersetting.
