The following is needed for std::complex<Real>:

All devices (even AMD CPU with intel OpenCL runtime) that support OpenCL and can consume SPIR or SPIRV can use the Eigen SYCL backend and consequently

\returns the rank of the matrix of which *this is the LU decomposition. * * \note This method has to determine which pivots should be considered

Get the permutation that was applied to columns of A

Swaps the values of \c *this and \a other. * Overloaded for performance: this version performs a \em shallow swap by swapping pointers and attribut

\brief Return a solver for the adjointed matrix. * * \returns an expression of the adjoint of the factored matrix * * A typical usage is t

\returns a view of the lower triangular matrix L */

\returns the stored value of the symbol */

Size returns current queue size. Can be called by any thread at any time.

\returns the value of the rotation angle in radian */

\internal * Resize the nonzero vector to \a size */
