Add multiple values to a vector.
vector | the vector to modify |
vectorIndices | mapping from index of the ublas vector (see param below) to index of the vector of this linear system |
smallVector | Ublas vector containing the values to be added |
N.B. Values which are not local (ie the row is not owned) will be skipped.

Computes y += ax, using the PETSc method VecAXPY (with appropriate arguments for the PETSc version).
y | the vector which is added to |
x | the vector which is scaled and added to y |
scaleFactor | the value 'a' above, the factor x is multiplied by. |
