	TVector x,
	TVector y,
	TMatrix a
)

Parameters

m  Int32
The number of rows in the matrix a.
n  Int32
The number of columns in the matrix a.
alpha  T
The scalar used to multiply the outer product.
x  TVector
A reference to a one-dimensional array containing the elements of the vector x.
y  TVector
A reference to a one-dimensional array containing the elements of the vector y.
a  TMatrix
A span that contains the elements of the matrix.
