The FloatSymPDBandFact type exposes the following members.

Constructors

	Name	Description
	FloatSymPDBandFact(FloatSymBandMatrix)	Constructs a FloatSymPDBandFact instance by factoring the given matrix. By default the condition number for the matrix will not be computed and will not be available from the ConditionNumber method.
	FloatSymPDBandFact(FloatSymBandMatrix, Boolean)	Constructs an FloatSymPDBandFact instance by factoring the given matrix, optionally estimating the condition number of the matrix.

Properties

	Name	Description
	Cols	Gets the number of columns in the matrix represented by the factorization.
	HalfBandwidth	Gets the half bandwidth of the factored symmetric banded matrix.
	IsGood	Gets a boolean value which is true if the matrix factorization succeeded and the factorization may be used to solve equations, compute determinants, inverses, and so on; otherwise false.
	IsPositiveDefinite	Gets a boolean value which is true if the matrix factored is positive definite; otherwise, false.
	Rows	Gets the number of rows in the matrix represented by the factorization.

Methods

	Name	Description
	Clone	Creates a deep copy of this factorization.
	ConditionNumber	Computes an estimate of the reciprocal of the condition number of a given matrix with respect to the one norm.
	Determinant	Computes the determinant of the factored matrix.
	Factor(FloatSymBandMatrix)	Factors the matrix A so that self represents the LU factorization of A. By default the condition number for the matrix will not be computed and will not be available from the ConditionNumber method.
	Factor(FloatSymBandMatrix, Boolean)	Factors the matrix A so that self represents the LU factorization of A.
	Inverse	Computes the inverse of the factored matrix.
	Solve(FloatMatrix)	Uses this factorization to solve the linear system AX = B.
	Solve(FloatVector)	Uses the LU factorization of self to solve the linear system Ax = b.
