Sparse matrix kernel ( #6035 )
...
* Subtle bug in kernel computation
Coefficient was being passed by reference and, therefore, was
being changed indirectly.
In the process, updated the code to be more generic to avoid rational
computation in the middle of matrix manipulation.
* sparse_matrix: fixed handling of 0 in add_var() and add()
particularly in add_var(), without the fix the user is responsible for checking
coefficients for 0.
