Parameters
- matrix DenseMatrix<T>
- The matrix that contains the elements of the new matrix.
- dimension Int32
- The number of rows and columns of the new matrix.
- startRow Int32
- The row in matrix of the first component of the new matrix.
- startColumn Int32
- The column in matrix of the first component of the new matrix.
- storedTriangle MatrixTriangle
- A MatrixTriangle value that indicates whether the elements of the symmetric matrix are stored in the upper or lower triangular portion of the block specified by startRow and startColumn.
- reuseComponentArray Boolean
- A boolean value that indicates whether the storage array used by matrix should be copied or reused for internal storage.
Type Parameters
- T
Return Value
SymmetricMatrix<T>A SymmetricMatrix<T>.
Exceptions
