The investigation of conditioning number of linear algebraic equation system for the problem of finding of electromagnetic field in the system of long conductors

The paper is dedicated to the numerical modelling of electromagnetic field in the system of long conductors. The analytical solution of 1d problem for integro-differential equation is presented. The proof of positive conditionality of operator is executed for differential as well for difference problem. The calculation of eigenvalues for linear algebraic system characterizing the stated problem and conditioning number of system under solution is made.
