[petsc-users] How to get a duoble array into petsc Vec?

[Morlighem, Mathieu (334H-Affiliate)]

Try this instead:

for(i=0;i<rows;i++)index[i]=i;
ierr=VecSetValues(petscvector,rows,index,doublearray,INSERT_VALUES); CHKERRQ(ierr);

Hi,

I am trying to put data form a double c array to an petsc vector. I tried to loop over each element like this petsc Vec[i] = double array[i], but I need a cast for that….has anybody an idea?

Thanks Jürgen
