Dense Matrix<T, TSlice, TStorage2D>.Multiply Method
Definition
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
Overload List
Multiply( | Multiplies this matrix on the right by a square Matrix<T>. |
Multiply( | Applies the linear operator to a vector. |
Multiply( | Multiplies two matrix objects. |
Multiply( | Multiplies two DenseMatrix<T, TSlice, TStorage2D> objects and stores the result in a third DenseMatrix<T, TSlice, TStorage2D>. |
Multiply(Matrix<T>)
public override DenseMatrix<T> Multiply(
Matrix<T> matrix
)
Parameters
Return Value
DenseMatrix<T>A reference to this instance, which is the product of the original DenseMatrix<T, TSlice, TStorage2D> with matrix.
Remarks
The matrix matrix must be square, and the number of rows and columns of matrix must be equal to the number of columns of this instance. Otherwise, an exception of type DimensionMismatchException is thrown.
Exceptions
Argument | matrix is null. |
Dimension | The number of rows of matrix does not match the number of columns in this matrix. -or- matrix is not square. |
Multiply(DenseMatrix<T>, DenseMatrix<T>)
public static DenseMatrix<T> Multiply(
DenseMatrix<T> matrix1,
DenseMatrix<T> matrix2
)
Parameters
- matrix1 DenseMatrix<T>
- The first DenseMatrix<T, TSlice, TStorage2D>.
- matrix2 DenseMatrix<T>
- The second DenseMatrix<T, TSlice, TStorage2D>.
Return Value
DenseMatrix<T>A DenseMatrix<T, TSlice, TStorage2D> that is the product of matrix1 and matrix2.
Remarks
The number of columns of matrix1 must be equal to the number of rows of matrix2. Otherwise, an exception of type DimensionMismatchException is thrown.
This method uses the BLAS routine DGEMM.
Exceptions
Argument | matrix1 is null. -or- matrix2 is null. |
Dimension | The number of columns of matrix1 does not equal the number of rows of matrix2. |
Multiply(DenseMatrix<T>, DenseMatrix<T>, DenseMatrix<T>)
public static DenseMatrix<T> Multiply(
DenseMatrix<T> matrix1,
DenseMatrix<T> matrix2,
DenseMatrix<T> resultMatrix
)
Parameters
- matrix1 DenseMatrix<T>
- A DenseMatrix<T, TSlice, TStorage2D> that is the left factor of the multiplication.
- matrix2 DenseMatrix<T>
- A DenseMatrix<T, TSlice, TStorage2D> that is the right factor of the multiplication.
- resultMatrix DenseMatrix<T>
- A DenseMatrix<T, TSlice, TStorage2D> that is to receive the result of the multiplication.
Return Value
DenseMatrix<T>A reference to resultMatrix.
Remarks
The number of columns of matrix1 must be equal to the number of rows of matrix2. The number of rows of matrix1 must be equal to the number of rows of resultMatrix. The number of columns of matrix2 must be equal to the number of columns of resultMatrix. Otherwise, an exception of type DimensionMismatchException is thrown.
This method uses the BLAS routine DGEMM.
Exceptions
Argument | matrix1 is null. -or- matrix2 is null. -or- resultMatrix is null. |
Dimension | The number of rows of matrix1 does not equal the number of rows of resultMatrix. -or- The number of columns of matrix1 does not equal the number of columns of resultMatrix. -or- The number of columns of matrix1 does not equal the number of rows of matrix2. |
