Tall-and-skinny QR factorization with approximate Householder reflectors on graphics processors
Springer (2020-01-24)We present a novel method for the QR factorization of large tall-and-skinny matrices that introduces an approximation technique for computing the Householder vectors. This approach is very competitive on a hybrid platform ...
