Hi I am trying to generate a matrix(nxn) from 3 arrays(1D) which I have read from 3 single textfiles:
PetscInt pcol[] (dimension of nz): points to the integer array of length nz that holds the column indices of the corresponding elements in pval PetscInt prow[] (dimesion of n) PetscScalar pval[] (dimension of nz) I tried this: MatSetValues(A,n,prow,nz,pcol,pval,INSERT_VALUES); MatAssemblyBegin(A,MAT_FINAL_ASSEMBLY); MatAssemblyEnd(A,MAT_FINAL_ASSEMBLY); Can I insert the hole data into matrix A or should I loop over it?
