I am trying to multiply two dense matrices using the Elemental interface. I fill the matrix using MatSetValue( ) like below:
for ( i = 0; i < Matrix.M; i++){ for ( j = 0; j < Matrix.N; j++) { PetscScalar temp = i + one + (j*three); MatSetValue(Matrix.A, i, j, temp, INSERT_VALUES); } } However, I seem to get the following error: [0]PETSC ERROR: No support for this operation for this object type [0]PETSC ERROR: Only ADD_VALUES to off-processor entry is supported But if I use ADD_VALUES, I get a different matrix depending on the number of processors used. The entries become multiplied by the number of processors. How do I reconcile this? <redir.aspx?REF=hVEx-ekIltbV6NDJuYjzplTZG3ymEirNPcO9eR2dIGrvJzCyE4XTCAFtYWlsdG86ZXJpYy5yb2JlcnRzb25AY2ZkcmMuY29t>
