LUT Class |
A class which encapsulates the functionality of an LU factorization.
For a matrix A, the LU factorization is a pair of lower triangular matrix L and upper triangular matrix U so that A = L*U.
In the Math.NET implementation we also store a set of pivot elements for increased numerical stability. The pivot elements encode a permutation matrix P such that P*A = L*U.
public abstract class LU<T> : ISolver<T> where T : struct, new(), IEquatable<T>, IFormattable
The LUT type exposes the following members.
Name | Description | |
---|---|---|
Determinant | Gets the determinant of the matrix for which the LU factorization was computed. | |
L | Gets the lower triangular factor. | |
P | Gets the permutation applied to LU factorization. | |
U | Gets the upper triangular factor. |
Name | Description | |
---|---|---|
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) | |
GetHashCode | Serves as the default hash function. (Inherited from Object) | |
GetType | Gets the Type of the current instance. (Inherited from Object) | |
Inverse | Returns the inverse of this matrix. The inverse is calculated using LU decomposition. | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) | |
Solve(MatrixT) | Solves a system of linear equations, AX = B, with A LU factorized. | |
Solve(VectorT) | Solves a system of linear equations, Ax = b, with A LU factorized. | |
Solve(MatrixT, MatrixT) | Solves a system of linear equations, AX = B, with A LU factorized. | |
Solve(VectorT, VectorT) | Solves a system of linear equations, Ax = b, with A LU factorized. | |
ToString | Returns a string that represents the current object. (Inherited from Object) |
