| 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. |
| cern.colt.matrix.objectalgo |
Object matrix algorithms such as print formatting, sorting, partitioning and statistics.
