public SymmetricMatrix MultiplyByTranspose()

Public Function MultiplyByTranspose As SymmetricMatrix

public:
SymmetricMatrix^ MultiplyByTranspose()

member MultiplyByTranspose : unit -> SymmetricMatrix 

Return Value

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 DenseMatrix.

This method uses the BLAS routine DSYRK.
