On some orthogonalization schemes in Tensor Train format
Olivier Coulaud, Luc Giraud, Martina Iannacito
In the framework of tensor spaces, we consider orthogonalization kernels to generate an orthogonal basis of a tensor subspace from a set of linearly independent tensors. In particu…

A robust GMRES algorithm in Tensor Train format
Olivier Coulaud, Luc Giraud, Martina Iannacito
We consider the solution of linear systems with tensor product structure using a GMRES algorithm. In order to cope with the computational complexity in large dimension both in term…
