Hi, 

i was wondering in MatSetValues, when i need to specify the number of columns, 
whether that is the number of column entries per row?

So, if i want to insert two rows at five entries each, do i specify 5 or 10 
for the number of columns?

So something like this:

m_ierr = MatSetValues(m_globalMatrix, //the matrix
       			    	     2, //the number of rows 
       			             GlobalRowIndices, //and their global indices
       			             5, //the number of columns
       			             GlobalColIndices, //and their global indices
       			             Values, //the value to be inserted
       			             INSERT_VALUES);

and where the size of GlobalRowIndices is of size 2 and the size of 
GlobalColIndices is 10 as well as the size of Values?


thanks
mat
