TriangularMultiplyInPlace<T>(MatrixTriangle, TransposeOperation, MatrixDiagonal, Int32, Array2D<T>, ArraySlice<T>)
Product of a triangular matrix and a vector.
public static void TriangularMultiplyInPlace<T>(
MatrixTriangle storedTriangle,
TransposeOperation transposeOperation,
MatrixDiagonal diagonal,
int n,
Array2D<T> a,
ArraySlice<T> x
)
Parameters
- storedTriangle MatrixTriangle
- Specifies whether the matrix is an upper or lower triangular matrix.
- transposeOperation TransposeOperation
- Specifies the operation to be performed on the matrix a.
- diagonal MatrixDiagonal
- Specifies whether or not a is unit triangular.
- n Int32
- The number of rows and columns in the matrix a.
- a Array2D<T>
- Reference to the first element in a one-dimensional array that contains the elements of the matrix.
- x ArraySlice<T>
- A reference to a one-dimensional array containing the elements of the vector x. The elements of x are overwritten with the result.
Type Parameters
- T
Remarks
This method is similar to the BLAS routine DTRMV.
