[petsc-users] Matrix assebly

[siddhesh godbole]

Hello,

I have created a matrix with initial values and i want to change the
elements of the same matrix and in the iterations column wise. how do i
insert new columns into the matrix when calls for assembly begin and end
have already been made?

I have used MatGetColumnVector to select which column to edit but how do i
store it back into the same matrix? because it seems it does not happen
otherwise.
