Thanks a lot, it's ok using the code PetscViewer viewer; PetscViewerASCIIOpen(PETSC_COMM_WORLD, K1.m, viewer); PetscViewerSetFormat(viewer, PETSC_VIEWER_ASCII_MATLAB); MatView(data-K1, viewer); but failed with the code MatView(data-K1, PETSC_VIEWER_MATLAB_WORLD); as the

weiwei, The easist way is run your petsc code with the option '-mat_view_matlab', and dump it into a file. Then use Matlab to load it for whatever you want to investigate. See petsc user manual on Using Matlab with PETSc. Hong On Mon, 10 Aug 2009, Weiwei Wang wrote: Dear All, I want to

You should really use the PetscViewerBinaryOpen() then use bin/ matlab/PetscBinaryRead() to read the matrices and vectors into Matlab. Barry On Aug 10, 2009, at 10:10 PM, Weiwei Wang wrote: Thanks a lot, it's ok using the code PetscViewer viewer;
