A1n b1\nA21 A22 ... A2n b2\n... ... ... ... ..\nAn1 An2 ... Ann bn\n\nPlease note that the algorithm computes correct values only for symmetric and positive-definite matrices A.\nIn the solution folder you can also find a utility to generate such matrices.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdimadeveatii%2Fconjugate-gradient-mpi-net-implementation","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdimadeveatii%2Fconjugate-gradient-mpi-net-implementation","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdimadeveatii%2Fconjugate-gradient-mpi-net-implementation/lists"}
