void RankUpdate(
int m,
int n,
T alpha,
ReadOnlySpan<T> x,
int incx,
ReadOnlySpan<T> y,
int incy,
Span<T> a,
int lda
)
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 ReadOnlySpan<T>
- A span containing the elements of the vector x.
- incx Int32
- The distance between elements in x.
- y ReadOnlySpan<T>
- A span containing the elements of the vector y.
- incy Int32
- The distance between elements in y.
- a Span<T>
- A span that contains the elements of the matrix.
- lda Int32
- The leading dimension of the matrix a.
Remarks
This method is similar to the BLAS routine DGER.
