There exist two implementing methods in the automatic differentiation , including the source transformation method and the operator overloading method 自动微分的实现方法包括源代码变换方法和运算符重载方法。
Finding a solution to a circuit can be somewhat difficult without using tricks or methods that make the circuit appear simpler. Circuit solutions are often simplified, especially with mixed sources, by transforming a voltage into a current source, and vice versa.
