Copy

public void InitialFactors(
	ref DoubleMatrix V,
	int k,
	ref DoubleMatrix W,
	ref DoubleMatrix H
)

Public Sub InitialFactors ( 
	ByRef V As DoubleMatrix,
	k As Integer,
	ByRef W As DoubleMatrix,
	ByRef H As DoubleMatrix

public:
virtual void InitialFactors(
	DoubleMatrix^% V, 
	int k, 
	DoubleMatrix^% W, 
	DoubleMatrix^% H
) sealed

abstract InitialFactors : 
        V : DoubleMatrix byref * 
        k : int * 
        W : DoubleMatrix byref * 
        H : DoubleMatrix byref -> unit

        W : DoubleMatrix byref * 
        H : DoubleMatrix byref -> unit

Parameters

V: Type: CenterSpace.NMath.CoreDoubleMatrix
The non-negative being factored
k: Type: SystemInt32
The number of columns in W and the number of rows in H.
W: Type: CenterSpace.NMath.CoreDoubleMatrix
The first factor. Should be V.Rows x k
H: Type: CenterSpace.NMath.CoreDoubleMatrix
The second factor. Should be k x V.Cols
