Dear All I am an absolute beginner to PetSc. I am trying to output PetSc vectors in a specific format. This may have been discussed before, but I have so far not found a solution.
For 2 or 3 vectors, I do this: /* now write it to file. I would like row 1 to be u, row 2 to be b, and row 3 to be u. that way I can use gnuplots surf, and also all my existin matlab code for plotting/analysis. */ PetscViewer viewer; // a Petsc file pointer. PetscViewerASCIIOpen(PETSC_COMM_WORLD,"ubx.dat",&viewer); VecView(u,viewer); // this comes out with information that I dont want, and in a column - I need to put it as a row. VecView(b,viewer); VecView(x,viewer); PetscViewerDestroy( &viewer ); However, I have not been able to get rid of the information about procs, and also the vectors u, b, and u need to be in row format as: 1 2 1 1 1 0 0 0 1 0 -1 2 -1 0 rather than what I have now: Vector Object: 1 MPI processes type: seq 1 2 1 1 1 etc.... Any suggestions on how to do this will be appreciated. thanks Sanjay
