public interface ILinearAlgebraProvider : ILinearAlgebraProvider<double>, ILinearAlgebraProvider<float>, ILinearAlgebraProvider<Complex>, ILinearAlgebraProvider<Complex32>
The ILinearAlgebraProvider type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AddArrays(T[], T[], T[]) |
Does a point wise add of two arrays z = x + y. This can be used
to add vectors or matrices.
(Inherited from ILinearAlgebraProvider<T>) |
| AddVectorToScaledVector(T[], T, T[], T[]) |
Adds a scaled vector to another: result = y + alpha*x.
(Inherited from ILinearAlgebraProvider<T>) |
| CholeskyFactor(T[], Int32) |
Computes the Cholesky factorization of A.
(Inherited from ILinearAlgebraProvider<T>) |
| CholeskySolve(T[], Int32, T[], Int32) |
Solves A*X=B for X using Cholesky factorization.
(Inherited from ILinearAlgebraProvider<T>) |
| CholeskySolveFactored(T[], Int32, T[], Int32) |
Solves A*X=B for X using a previously factored A matrix.
(Inherited from ILinearAlgebraProvider<T>) |
| ConjugateArray(T[], T[]) |
Conjugates an array. Can be used to conjugate a vector and a matrix.
(Inherited from ILinearAlgebraProvider<T>) |
| DotProduct(T[], T[]) |
Computes the dot product of x and y.
(Inherited from ILinearAlgebraProvider<T>) |
| EigenDecomp(Boolean, Int32, T[], T[], Complex[], T[]) |
Computes the eigenvalues and eigenvectors of a matrix.
(Inherited from ILinearAlgebraProvider<T>) |
| FreeResources | Frees memory buffers, caches and handles allocated in or to the provider. Does not unload the provider itself, it is still usable afterwards. |
| InitializeVerify | Initialize and verify that the provided is indeed available. If not, fall back to alternatives like the managed provider |
| IsAvailable | Try to find out whether the provider is available, at least in principle. Verification may still fail if available, but it will certainly fail if unavailable. |
| LUFactor(T[], Int32, Int32[]) |

(Inherited from ILinearAlgebraProvider<T>) |
| LUInverse(T[], Int32) |
Computes the inverse of matrix using LU factorization.
(Inherited from ILinearAlgebraProvider<T>) |
| LUInverseFactored(T[], Int32, Int32[]) |
Computes the inverse of a previously factored matrix.
(Inherited from ILinearAlgebraProvider<T>) |
| LUSolve(Int32, T[], Int32, T[]) |

to multiply elements of vectors or matrices.
(Inherited from ILinearAlgebraProvider<T>) |
| PointWisePowerArrays(T[], T[], T[]) |
