The purpose is detection and correction of calculation errors occurred due to transient hardware faults. Usine the proposed method, the fault-tolerant version of Faddeeva algorithm is designed in this paper. The computational complexity of new algorithm is increased approximately on O(N2~)) multiply-add operations in comparison with the original one. However, new algorithm enables to detect and to correct a single error in an arbitrary row or column of input data matrices at the each algorithm step. Hence, it is possible to correct up to N2~) and (N2~)/2+N P) single errors during realization of whole Jordan-Gauss and Faddeeva algorithms respectively. Finally, the results of experimental verification of the proposed algorithm are represented. 0aUkłady elektroniczne. 0aMateriały konferencyjne.22aInternational Conference on Signals and Electronic Systems ICSES 2002d(2002 ;cWrocław / Świeradów Zdrój, Polska).pICSES'20020 iW:tICSES'2002 : proceedings of the International Conference on Signals and Electronic Systems, Wrocław - Świeradów Zdrój, Poland 24-27 September 2002 / [ed. by R.
