Constructors
 NameDescription
Public methodFloatBandFact(FloatBandMatrix) Constructs a FloatBandFact 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.

Properties
 NameDescription
Public propertyCols Gets the number of columns in the matrix represented by the factorization.
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 propertyIsSingular Gets a boolean value which is true if the matrix factored is singular; otherwise, false.
Public propertyLowerBandwidth Gets the lower bandwidth of the factored banded matrix.
Public propertyRows Gets the number of rows in the matrix represented by the factorization.
Public propertyUpperBandwidth Gets the upper bandwidth of the factored banded matrix.
