C#
void RankUpdate(
	int m,
	int n,
	T alpha,
	ArraySlice<T> x,
	ArraySlice<T> y,
	Array2D<T> 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  ArraySlice<T>
A reference to a one-dimensional array containing the elements of the vector x.
y  ArraySlice<T>
A reference to a one-dimensional array containing the elements of the vector y.
a  Array2D<T>
Reference to the first element in a one-dimensional array that contains the elements of the matrix.

Remarks

This method is similar to the BLAS routine DGER.
