| Field Summary | |
| final public static double | TINY
| | double | d
| | int | indx
| | double | twod
|
| Constructor Summary | |
| public | LUDecomp(Matrix m)
LU Decomposition of a Matrix a. |
| Method Summary | |
| public double[] | backSubstitute(double[] data)
Perform back substitution based on this LU decomposed matrix. | | public double | ludeterminant()
| | public Matrix | luinvert()
Return the inverse of the original matrix used in the construction
of this LUDecomp object. | | public String | toString()
Render the contents of this LU decomposition into a string
primarily for debugging use. |
| TINY | | final public static double TINY(Code) | | |
| LUDecomp | | public LUDecomp(Matrix m) throws SingularException, NotSquareException(Code) | | LU Decomposition of a Matrix a. Specalised case of a Matrix
operator. This constructor performs the LU decomposition of
the supplied matrix and creates an instance of its decomposition.
|
| backSubstitute | | public double[] backSubstitute(double[] data) throws SizeMismatchException(Code) | | Perform back substitution based on this LU decomposed matrix. This
effectively solves a set of N linear equations A.X = B.
Parameters:
data - The 1 x N data vector. (RHS vector B) |
| ludeterminant | | public double ludeterminant()(Code) | | |
| luinvert | | public Matrix luinvert() throws SizeMismatchException(Code) | | Return the inverse of the original matrix used in the construction
of this LUDecomp object. Simply involves back substitution of the
identity matrix.
|
| toString | | public String toString()(Code) | | Render the contents of this LU decomposition into a string
primarily for debugging use.
