ComplexMatrix

final public class ComplexMatrix extends Matrix (Code)

This class represents an optimized Matrix matrix implementation for Complex complex numbers.

Instances of this class can be created from ComplexVector , either as rows or columns if the matrix is transposed. For example:[code] ComplexVector column0 = ComplexVector.valueOf(...); ComplexVector column1 = ComplexVector.valueOf(...); ComplexMatrix M = ComplexMatrix.valueOf(column0, column1).transpose(); [/code]
