In statistics, an expectation-maximization (EM) algorithm is a method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. EM is an iterative method which alternates between performing an expectation (E) step, which computes the expectation of the log-likelihood evaluated using the current estimate for the latent variables, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.

说明：  程序中 时间结点错开了一个位子； （2）没有注意保存中间结果，程序画出的只是之后一个小时间段结果。(Staggered in time node program a seat (2) lack of attention to hold intermediate results, the program just to draw a small period of time after the results.)

设计一个数字滤波器，在频率低于 的范围内，低通幅度特性为常数，并且不低于0.75dB。在频率 和 之间，阻带衰减至少为20dB。 (1)试求满足这些条件的最低阶Butterworth滤波器。(Design a digital filter, in the range of frequencies below the low-pass amplitude characteristic is constant, and not less than 0.75dB. Between the frequency and stop-band attenuation of at least 20dB. (1) Determine the lowest-order Butterworth filter to meet these conditions.)

Matlab的一大缺陷是不注重数据结构，其结构体无比难用，所以我们这里将尽可能使用矩阵进行处理，而参数较多时，我们也只是简单的将其放入到元胞数组中，不优雅之处，敬请见谅。
