说明：  WGS84到BJ54坐标转换的四参数模型，可以求出四参数和转换坐标(WGS84 coordinate transformation to the BJ54 The four parameter model, four parameters can be calculated and converted coordinates)

一共5个代码，其中aufgabe和lms的功能是输入一个脉冲信号，根据不同的系统参数，得出输出信号。 cordic是一个算角度旋转的方法。 gray和graydecode是输入一个数字，对应输出每次只变一位的2进制输出信号。 因为我还是个学生，可能代码比较简单，希望站长谅解，谢谢！我真心希望能够成为该站的一员，学习到有用的知识。(A total of five codes, which aufgabe and lms function is a pulse input signal, depending on the system parameters, derived output signal. cordic is a rotation angle calculation method. gray and graydecode is to enter a number, corresponding to a time become an output of two binary output signals. Because I was a student, you may code for relatively simple hope that owners understand, thank you! I really hope to be a member of the station, to learn useful knowledge.)
