Hey all,
I have to apply cusolver routine cusolverDnDgesvd on a rectangular matrix of size MN where M is greater then N. I would like U , S and Vt to have sizes of M * K , KK, K*N respectively .
It suggests in tutorial that one should give ‘S’ to parameters for jobu and jobvt which leads U to be size of MK and Vt to be KN . But i also read that only ‘A’ parameter is supported in Cuda 7.0 . But ‘A’ parameter leads U and Vt to be of MM and NN.
I am pretty confused since I do not much experience cuda libraries. In short, i would like to learn whether it is possible to factorize a rectangular matrix by a chosen rank with cusolverDnDgesvd routine.
Thanks a lot,
