	callback method for evaluating the jacobian for the nonlinear terms in a given row

Detailed Description

A square model where we pretend that the second constraint is completely nonlinear.

\[ x1 + x2 = 10 \]

\[ x1 - x2 = 0 \]

\[ x1 + x2 \leq 9 \]

In a second case we change the Rhs in the inequality to 11 so the model becomes feasible.

For more information about the individual callbacks, please have a look at the source code.

evaluateNonlinearTerm()

square2.SquareModelData.evaluateNonlinearTerm	(		self,
			x,
			rowno,
			ignerr,
			thread )

callback method for evaluating the nonlinear terms in a given row

Parameters

x	the solution vector that needs to be evaluated.
rowno	the number for the row in which the nonlinear term exists.
ignerr	a boolean to indicate whether the current point is safe or unsafe.
thread	the index of the thread from which this method is being called from.

Returns

the value of the nonlinear terms.

Notes: an error in the evaluation is reported by calling errorInEvaluation()

evaluateNonlinearJacobian()

square2.SquareModelData.evaluateNonlinearJacobian	(		self,
			x,
			rowno,
			jacnum,
			ignerr,
			thread )

callback method for evaluating the jacobian for the nonlinear terms in a given row

Parameters

x	the solution vector that needs to be evaluated.
rowno	the number for the row in which the nonlinear term exists.
jacnum	vector with a list of column numbers for the nonlinear nonzero Jacobian elements in the row.
ignerr	a boolean to indicate whether the current point is safe or unsafe.
thread	the index of the thread from which this method is being called from.

Returns

a vector the length of jacnum that contains the jacobian values for the referenced elements.
