I need to compute the cholesky decomposition for a very sparse matrix.
The cusolver library can compute the cholesky decomposition for sparse matrix using the cusolverSpDcsrcholFactor function.
The result is stored in the internal opaque structure csrcholInfo but I can’t find any function to get this result.
The function to get the result for a decomposition is provided for the LU decomposition using the combination of cusolverSpXcsrluNnz and cusolverSpDcsrluExtract functions.
Is there a way to get the cholesky decomposition result from the internal opaque structure ?
Is it planned for the future cusolver release to provide a function to extract the cholesky decomposition result from the internal structure like the cusolverSpDcsrluExtract function used for LU decomposition ?
