*_gpu versions of the gesvd routines

I have some code which is performing an svd calculation followed by a least squares calculation. I don't want to have to transfer the arrays twice. Is there some reason why the svd routines don't offer *_gpu versions so that I can call two functions sequentially, prefaced by just one device->gpu cop...

Re: Solving least squares problems for underdetermined systems

That would be absolutely fantastic if that could be added in. Indeed ... there are absolutely no CUDA implementations for underdetermined problems anywhere. It looks like CULA used to support them ... but near as I can tell, that project is dead. Is there anything I can do from my end to advance the...

Solving least squares problems for underdetermined systems

Greetings, I have two related questions re: solving the least squares problem (with routines like `magma_dgels`) for under-determined systems of equations (i.e. cases where m<n; which of course, is not currently supported by Magma): 1) Is support for solving problems of this type anywhere on the hor...
