ILMatheig Method (InArraySingle)

public static RetArray<fcomplex> eig(
	InArray<float> A
)

Public Shared Function eig ( 
	A As InArray(Of Single)
) As RetArray(Of fcomplex)

Dim A As InArray(Of Single)
Dim returnValue As RetArray(Of fcomplex)

returnValue = ILMath.eig(A)

Parameters

A

Type: ILNumericsInArraySingle
Input matrix. Size [n x n].

Return Value

The eigenvalues of A are found by use of the Lapack functions dgeevx, sgeevx, cgeevx and zgeevx.

The vector returned is fcomplex, since A may be nonsymmetric. Use eigSymm(InArraySingle) for computing real eigenvalues of symmetric matrices.

A is internally balanced first. This includes permutations and scaling of A in order to improve the conditioning of the eigenvalues.
