This is a LSQR-CUDA implementation written by Lawrence Ayers under the supervision of Stefan Guthe of the GRIS institute at the Technische Universität Darmstadt. The LSQR library was authored Chris Paige and Michael Saunders.
After tests, some keywords only exist in the version 11.x of CUDA. For example, CUSPARSE_MV_ALG_DEFAULT in matrixCUSPARSE.cu.
So I hope the author can modify the Requirements in README for "CUDA (nvcc) v11". Thanks! :)
