Overload List
TriangularEstimateCondition(MatrixNorm, MatrixTriangle, MatrixDiagonal, Int32, ReadOnlySpan<Complex<Double>>, Int32, Double, Int32)
Approximates the reciprocal of the condition number of a complex triangular matrix.
public override void TriangularEstimateCondition(
MatrixNorm norm,
MatrixTriangle storedTriangle,
MatrixDiagonal diag,
int n,
ReadOnlySpan<Complex<double>> a,
int lda,
out double 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<Complex<Double>>
- A complex array that contains the elements of the matrix.
- lda Int32
- The leading dimension of the matrix a.
- rcond Double
- On return, an estimate for the reciprocal of the condition number of the matrix.
- info Int32
- On return, indicates error conditions.
