[petsc-users] set a Vec as row or column of a Mat

I have a petsc Vec object ( say length 3). I want to use its entries as 
the  column of a Petsc Mat (say 3x3).
Is there an obvious way to do this ?
I could only think of first  copying the entries of the Vec into an 
array with VecGetValues, and then use it to set the values of the column 
of the Mat.
In case it is relevant, I am doing a  sweep of a direction splitting 
method over a square, and I want to store the solution (vector) of each 
one dimensional problem in a Mat.
