public SymmetricMatrix MultiplyByTranspose()
Public Function MultiplyByTranspose As SymmetricMatrix
member MultiplyByTranspose : unit -> SymmetricMatrix
the product of this DenseMatrix
Some applications, for example the solution
of a least squares problem using normal equations,
require the product of a matrix with its own
transpose. This method performs this operation.
The resulting matrix is always symmetrical and positive
definite. This is why a SymmetricMatrix
is returned, rather than a more general
This method uses the BLAS routine DSYRK.
