Parameters

storageTriangle

Type: Extreme.MathematicsMatrixTriangle
Specifies whether the matrix is an upper or lower triangular matrix.

n

Type: SystemInt32
The number of rows and columns in the matrix a.

alpha

Type: T
The scalar used to multiply the outer product.

x

Type: TVector
A reference to a one-dimensional array containing the elements of the vector x.

y

Type: TVector
A reference to a one-dimensional array containing the elements of the vector y.

a

Type: TMatrix
Reference to the first element in a one-dimensional array that contains the elements of the matrix.

This method is similar to the BLAS routine DSYR2.
