Syntax

public DoubleComplexBandMatrix(
	DoubleComplexMatrix A,
	int lowerBandwidth,
	int upperBandwidth
)

Public Sub New ( 
	A As DoubleComplexMatrix,
	lowerBandwidth As Integer,
	upperBandwidth As Integer
)

public:
DoubleComplexBandMatrix(
	DoubleComplexMatrix^ A, 
	int lowerBandwidth, 
	int upperBandwidth
)

new : 
        A : DoubleComplexMatrix * 
        lowerBandwidth : int * 
        upperBandwidth : int -> DoubleComplexBandMatrix

A DoubleComplexMatrix: A general matrix.
lowerBandwidth Int32: The number of subdiagonals to extract. This is also the lower bandwidth of the resulting banded matrix.
upperBandwidth Int32: The number of superdiagonals to extract. This is also the upper bandwidth of the resulting banded matrix.

Exceptions

Exception	Condition
InvalidArgumentException	Thrown if the number of rows of A is less than the bandwidth of resulting banded matrix.

Remarks

The main diagonal is extracted along with lowerBandwidth subdiagonals and upperBandwidth superdiagonals.
