"Cusparse" ,solve the sparse matrix Linear equations Ax=b

Accelerated Computing HPC Compilers Legacy PGI Compilers

As the title shows,I want to use the content of the PGI compiler to solve the sparse linear equations Ax=b.
I noticed the cuSparse Library,however,I only find the “cusparseSgtsv” series of functions that are used to solve the three-diagonal sparse matrix,no “inv” or “LU” to solve the sparse matrix equation.

Hope to get some help ,thanks~

I’m pretty sure the tridiagonal routines do the factor and solve together in one call.

But, I need a more general case, not just the three-diagonal sparse coefficient matrix A, but all the sparse matrices A…
