The FloatSymPDBandFact type exposes the following members.

Constructors
  NameDescription
Public methodFloatSymPDBandFact(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.
Public methodFloatSymPDBandFact(FloatSymBandMatrix, Boolean)
Constructs an FloatSymPDBandFact instance by factoring the given matrix, optionally estimating the condition number of the matrix.

Properties
  NameDescription
Public propertyCols
Gets the number of columns in the matrix represented by the factorization.
Public propertyHalfBandwidth
Gets the half bandwidth of the factored symmetric banded matrix.
Public propertyIsGood
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.
Public propertyIsPositiveDefinite
Gets a boolean value which is true if the matrix factored is positive definite; otherwise, false.
Public propertyRows
Gets the number of rows in the matrix represented by the factorization.

Methods
  NameDescription
Public methodClone
Creates a deep copy of this factorization.
Public methodConditionNumber
Computes an estimate of the reciprocal of the condition number of a given matrix with respect to the one norm.
Public methodDeterminant
Computes the determinant of the factored matrix.
Public methodFactor(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.
Public methodFactor(FloatSymBandMatrix, Boolean)
Factors the matrix A so that self represents the LU factorization of A.
Public methodInverse
Computes the inverse of the factored matrix.
Public methodSolve(FloatMatrix)
Uses this factorization to solve the linear system AX = B.
Public methodSolve(FloatVector)
Uses the LU factorization of self to solve the linear system Ax = b.
