nrn_buildjacobian_thread()

template<typename F >

void coreneuron::detail::nrn_buildjacobian_thread	(	NewtonSpace *	ns,
		int	n,
		int *	index,
		F const &	func,
		double *	value,
		double **	jacobian,
		_threadargsproto_
	)

Calculate the Jacobian matrix using finite central differences.

Creates the Jacobian matrix by computing partial derivatives by finite central differences. If the column variable is nonzero, an increment of 2% of the variable is used. STEP is the minimum increment allowed; it is currently set to 1.0E-6.

Parameters

	n	number of variables
	x	pointer to array of addresses of the solution vector elements
	p	array of parameter values
	func	callable that computes the deviation from zero of each equation in the model
	value	pointer to array of addresses of function values
[out]	jacobian	computed jacobian matrix
