JACOBIAN: contains the Jacobian matrix (only if the OUTJAC option is used). ... If boundary constraints are used, this observation contains the upper bounds. Those parameters not subjected to upper ...

The n columns of the Jacobian matrix must correspond to the order of the n decision variables listed in the DECVAR statement. To specify the values of nonzero derivatives, the variables specified in ...

The Jacobian matrix representing all interactions among pairs of species and locations is highly structured. It is made of the sub-matrices A, M and D.
