如何用ARMA模型拟合股价时间序列?我在MATLAB2007上建立了ARMA模型，分析股价时间序列，模型已经有了，但是不知道如何得到拟合输出时序。分析需要拟合输出图，作拟合误差分析。(stock price estimation)

卡尔曼直流信号滤波 附波形图 有需要可以看看(Kalman DC signal filtering with waveform there is a need to look at)

时变信道的频率选择性和时变性。系统的输入是一个BPSK信号。系统的时变特性使BPSK信号作为时间的函数，发生衰减和相位旋转。(Time-varying channel frequency selectivity and time variability. Input to the system is a BPSK signal. System is time-varying characteristics make BPSK signal as a function of time, the occurrence of attenuation and phase rotation.)

说明：  一个数如果恰好等于它的因子之和，这个数就称为“完数”。例如6=1＋2＋3.编程 　　　 找出1000以内的所有完数。 (If a number is just equal to the sum of its factors, this number is called &quot End of a few.&quot For example 6 = 1+2+3. Programmatically find all finished within a number of 1000.)

改程序可以对信号进行emd分解，直接得到imf和hilbert谱(Change the program can signal emd decomposition directly from the imf and the hilbert spectrum)
