Finite difference approximations of first order derivatives of complex-valued functionsAshyralyyev, CharyyarÖztürk, BeyzaAshyralyev, A.Sadybekov, M.Lukashov, A.In this study, we generalize the well-known finite difference method to compute derivatives of a real-valued function to approximate complex derivatives wz and wz for complex-valued function w. Exploring different combinations of terms, we derive several approximations to compute the first order derivatives of complex-valued function. The first, second, third and fourth order of accuracy finite differences to calculate derivatives are studied. Error analysis in test examples are carried out by using Matlab program.American Institute of Physics Inc.2018Conference Objecthttps://rdlopen.rawdatalibrary.net/r/gumushane/14976https://doi.org/10.1063/1.5049048978-073541713-70094-243XenAIP Conference Proceedingsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/conferenceObjecthttps://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/14976
