Greetings,
I am working on implementing some conversions from complex Eigen matrices
to viennacl matrices. I understand there is no native complex data types
but instead expanded to have real/imaginary components in every other
column.
That said, I have run in to a problem when trying to use the copy command.
If I want to copy a matrix_slice object I am able to do it directly to a
Eigen::Matrix object
Eigen::MatrixXf Am;
viennacl::matrix_slice<viennacl::matrix<float> > Av;
viennacl::copy(Av, Am);
However, if I try to copy to a 'real' component of an Eigen Matrix, which
is essentially a MatrixXf object I get an error.
Eigen::MatrixXcf Am;
viennacl::matrix_slice<viennacl::matrix<float> > Av;
viennacl::copy(Av, Am.real());
even explicitly casting the object as Eigen Matrix type results in error:
viennacl::copy(Av, (Eigen::Matrix<float, Eigen::Dynamic,
Eigen::Dynamic>)Am.real());
error: no matching function for call to
‘copy(viennacl::matrix_slice<viennacl::matrix<float, viennacl::row_major>
>&, Eigen::Matrix<float, -1, -1>)’
viennacl::copy(A_sub, (Eigen::Matrix<float, Eigen::Dynamic,
Eigen::Dynamic>)(Am.real()));
Any thoughts why this would be the case?
Thanks,
Charles
