Hi,

It would be great if you provide small testcase to reproduce this issue on our side. Maybe there are some problems in matrix structure, maybe some input parameters like iparm are incorrect, and maybe condition number of input matrix is really huge. To choose correct answer we need to run testcase.

With best regards,

Also I think there cannot be a mistake with iparm as it is solving correctly for lesser(magnitudewise) coefficients of A matrix.

Thank you for the reply.

You could send .cpp example or file with ia, ja, a, rhs, iparm and correct solution arrays. Any variant would be convenientfor us if we reproduce your issue.

With best regards,

1) 3bricks......smaller magnitude coefficient + small size of matrix

2) 3bricks_diff._coefficients...larger magnitude coefficient + small size of matrix

3) Increased_size_of_matrix...smaller magnitude coefficient + larger size of matrix

Once again thanks for the reply and the help
