Parameters

alpha: Type: System..::..Single
Multiplier for the vector-matrix product of this matrix with the vector vector.

vector: Type: Extreme.Mathematics..::..SingleVector
A SingleMatrix.

trans: Type: Extreme.Mathematics..::..TransposeOperation
A TransposeOperation value that specifies the operation, if any, to be performed on this instance before the multiplication.

beta: Type: System..::..Single
Multiplier for the vector resultVector.

resultVector: Type: Extreme.Mathematics.LinearAlgebra..::..SingleDenseVector
The DenseVector that is to contain the result of the multiplication.

Return Value

The vector resultVector.

Remarks

This method uses the level 2 BLAS routines DGEMV and DTRMV.
