We describe the main design features of DSJM ( D etermine S parse J acobian M atrices), a software toolkit written in standard C++ that enables direct determination of sparse Jacobian matrices.

N=100 and M=1000. My current problem is just that writing the for-loops that produce these small Jacobian blocks is a drag, and hard to adapt to new models. Calculating all those indices is making me crazy!
