DoubleComplexMatrixDiagonal(Int32) Method

Returns a vector view of a diagonal of this matrix.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public DoubleComplexVector Diagonal(
	int k
)

Public Function Diagonal ( 
	k As Integer
) As DoubleComplexVector

public:
DoubleComplexVector^ Diagonal(
	int k
)

member Diagonal : 
        k : int -> DoubleComplexVector

DoubleComplexVector
A vector view of the specified diagonal.

Remarks

If k is zero, the main diagonal of the matrix is returned. If k is positive, the returned vector v satisfies:

<c>v[i] = this[i,i+k]</c>

If k is negative, the returned vector v satisfies:

v[i] = this[i-k,i]
