| Abstract: | Gauss projection numerical calculation for complex transformation is simple and quick,so that it is important for engineering applications.From the numerical point of view,using the computer algebra system such as Mathcad,Matlab and Mathematica,Gauss projection on the complex transformation has been improved: simply create transformation formula was calculated without creating inverse transform formula;for complex equations,finding roots of functions directly used to the system;on the complex integration,studing the integral series of analysis,elliptic integral function method and the direct integration method. |
