BP预测

说明：  gps c/a码的产生，是一个小的MATLAB代码，希望对你有用(c/a code generation)

分数阶傅立叶变换，可用于LFM信号的相干源信号的估计(Fractional Fourier Transform can be used for LFM signal of the coherent source signal estimate)

求解Lambert问题。 输入：轨道上两个点的位矢R1、R2，以及从R1到R2所用的时间t(缺点是脉冲太大)。 输出：质点在R1端点的速度V1，质点在R2端点的速度V2. 此函数用于：在给定轨道上两个点的位矢R1、R2，以及从R1到R2所用的时间t。求解V1、V2。再调用前面的函数就可以确定轨道根数，及任意时刻质点的状态。(To solve the Lambert problem. Input: track two-point position vector R1, R2, and R1 to R2 used in the time t (The disadvantage is that the pulse is too large). Output: particle R1 endpoint speed V1, the particle in the R2 endpoint speed V2. This function is used: two points in a given orbit position vector R1, R2, and from R1 to R2 with the time t. Solve the V1 and V2. And then call the previous function can determine the orbital elements, and any moment of the particle' s state.)

DFT和FFT的matlab实现及算法差异的证明，如复杂度等。（精度、不同长度的序列等）。(DFT and FFT algorithm matlab realize the difference and proved as complex and so on. (Accuracy, sequences of different lengths, etc.).)

使用matlab实现对excel文档的写操作，以写学生成绩报告为例(Use matlab to achieve excel document write operation to write the report as an example of student achievement)

说明：  实现ASK DPSK 调制解调的matlab 仿真(to come true ASK DPSK)
