Assembly: NMath (in NMath.dll) Version: 7.4
SyntaxParameters
- A DoubleHermitianBandMatrix
- An Hermitian banded matrix.
Return Value
DoubleAn estimate of the reciprocal of the condition number.
Remarks
The condition number of a matrix
A is:
where AInv is the inverse of the matrix A. This function
returns an estimate of the reciprocal of the condition number, rho = 1/kappa.
C#
kappa = ||A|| ||AInv||
