Overload List

TriangularEstimateCondition(MatrixNorm, MatrixTriangle, MatrixDiagonal, Int32, ReadOnlySpan<T>, Int32, T, Int32)

Approximates the reciprocal of the condition number of a complex triangular matrix.
C# 
public override void TriangularEstimateCondition(
	MatrixNorm norm,
	MatrixTriangle storedTriangle,
	MatrixDiagonal diag,
	int n,
	ReadOnlySpan<T> a,
	int lda,
	out T rcond,
	out int info
)

Parameters

norm  MatrixNorm
A MatrixNorm value that specifies which norm to use in the expression for the condition number.
storedTriangle  MatrixTriangle
A MatrixTriangle value that indicates whether the matrix is upper or lower triangular.
diag  MatrixDiagonal
A MatrixDiagonal value that indicates whether the matrix is unit diagonal.
n  Int32
The number of rows and columns of the matrix.
a  ReadOnlySpan<T>
A complex array that contains the elements of the matrix.
lda  Int32
The leading dimension of the matrix a.
rcond  T
On return, an estimate for the reciprocal of the condition number of the matrix.
info  Int32
On return, indicates error conditions.
