Solves the linear system AX = B.
Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
SyntaxParameters
- A FloatMatrix
- A coefficient matrix.
- B FloatMatrix
- The matrix of right hand sides. B must have the same number of rows as the matrix A.
Return Value
FloatMatrixA matrix with the same number of columns as B containing the solutions.
Exceptions| Exception | Condition |
|---|---|
| MatrixNotSquareException | Thrown if the matrix is not square. |
| SingularMatrixException | Thrown if the matrix is singular. |
| MismatchedSizeException | Thrown if the number of rows in B is different than the number of rows in the matrix A. |
Remarks
The ith column of X, X(i), is
the solution to the equation AX(i) = B(i), where
B(i) is the ith column of B.
Note that a FloatLUFact instance is created with each call. If you are calling Solve() repeatedly (inside a loop, for example), and the coefficient matrix A is not changing between calls, this is more efficient:Example
