public class SparseCCDComplexMatrix2D
Sparse column-compressed 2-d matrix holding complex elements. First see the package summary and javadoc tree view to get the broad picture.
Implementation:
Internally uses the standard sparse column-compressed format.
Note that this implementation is not synchronized.
