"In Electrical Impedance Tomography various optimization techniques are in use. For their successful application it is often usefull to calculate sensitivities needed in Jacobian matrix to accelerate particular iterative process. The paper presents and compares two methods of Jacobian determination, above all from the CPU\u2013time requirements standpoint while the Matlab language is utilized. The first method results from a reciprocity theorem, the second one from the nodal\u2013analysis\u2013equations differentiation."@en . "P(GA102/03/1108), V, Z(MSM 262200011), Z(MSM 262200022)" .
