void eval	(	doublereal *	x0,
		doublereal *	resid0,
		double	rdt
	)

Evaluate the Jacobian at x0.

The unperturbed residual function is resid0, which must be supplied on input. The third parameter 'rdt' is the reciprocal of the time step. If zero, the steady-state Jacobian is evaluated.

The array of residual values at x0 is supplied as an input.

doublereal * ptrColumn ( size_t j )

virtualinherited

Return a pointer to the top of column j, column values are assumed to be contiguous in memory.

The LAPACK bandstructure has column values which are contiguous in memory:

    On entry, the matrix A in band storage, in rows KL+1 to
    2*KL+KU+1; rows 1 to KL of the array need not be set.
    The j-th column of A is stored in the j-th column of the
    array AB as follows:
    AB(KL + KU + 1 + i - j,j) = A(i,j) for max(1, j - KU) <= i <= min(m, j + KL)

This routine returns the position of AB(1,j) (fortran-1 indexing) in the above format

So to address the (i,j) position, you use the following indexing:

double *colP_j = matrix.ptrColumn(j); double a_i_j = colP_j[kl + ku + i - j];

Parameters

j	Value of the column

Returns: Returns a pointer to the top of the column
