Syntax Public Function GetU As Complex(,)
public:
array<Complex,2>^ GetU()
member GetU : unit -> Complex[,]
Return Value
Type:
Complex
A
Complex matrix containing
U,
the unit upper triangular portion of the
LU factorization of
A.
Remarks
Scaled partial pivoting is used to achieve the
LU
factorization. The resulting factorization is such that
, where
A is the input matrix
a,
P is the
permutation matrix returned by
GetPermutationMatrix,
L is the lower triangular matrix returned by
GetL, and
U is the unit upper triangular matrix
returned by
GetU.
