Dense Matrix<T>.Add Outer Product In Place Method
Definition
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
Overload List
Add | Updates a matrix with the outer product of a vector and itself. |
Add | Updates a matrix with the scaled outer product of a vector and itself. |
Add | Updates a matrix with the outer product of two vectors. |
Add | Updates a matrix with the scaled outer product of two vectors. |
AddOuterProductInPlace(Vector<T>)
public DenseMatrix<T> AddOuterProductInPlace(
Vector<T> vector
)
Parameters
Return Value
DenseMatrix<T>A reference to this instance.
Remarks
The matrix must be square. The length of the vector vector must equal the number of rows and columns of this matrix. Otherwise, an exception of type DimensionMismatchException is thrown.
This operation is sometimes called vector rank-1 update.
Exceptions
Dimension | The length of vector does not equal the number of rows and columns of the matrix. |
AddOuterProductInPlace(T, Vector<T>)
public DenseMatrix<T> AddOuterProductInPlace(
T factor,
Vector<T> vector
)
Parameters
Return Value
DenseMatrix<T>A reference to this instance.
Remarks
The matrix must be square. The length of the vector vector must equal the number of rows and columns of this matrix. Otherwise, an exception of type DimensionMismatchException is thrown.
This operation is sometimes called vector rank-1 update.
Exceptions
Argument | vector is null. |
Dimension | The length of vector does not equal the number of rows and columns of the matrix. |
AddOuterProductInPlace(Vector<T>, Vector<T>)
public DenseMatrix<T> AddOuterProductInPlace(
Vector<T> left,
Vector<T> right
)
Parameters
Return Value
DenseMatrix<T>A reference to this instance.
Remarks
The length of the vector left must equal the number of rows of this matrix. The length of the vector right must equal the number of columns of this matrix. If either condition is violated, an exception of type DimensionMismatchException is thrown.
This operation is sometimes called left rank-1 update.
Exceptions
Argument | left is null. -or- right is null. |
Dimension | The length of left does not equal the number of rows in this matrix, or the length of left does not equal the number of columns. |
AddOuterProductInPlace(T, Vector<T>, Vector<T>)
public DenseMatrix<T> AddOuterProductInPlace(
T factor,
Vector<T> left,
Vector<T> right
)
Parameters
- factor T
- The scale factor.
- left Vector<T>
- The first (column) vector.
- right Vector<T>
- The second (row) vector.
Return Value
DenseMatrix<T>A reference to this instance.
Remarks
The length of the vector left must equal the number of rows of this matrix. The length of the vector right must equal the number of columns of this matrix. If either condition is violated, an exception of type DimensionMismatchException is thrown.
This operation is sometimes called left rank-1 update.
Exceptions
Argument | left is null. -or- right is null. |
Dimension | The length of left does not equal the number of rows in this matrix, or the length of left does not equal the number of columns. |
