根据伪随机序列理论，由混合同余法产生均匀分布的随机数，进而根据中心极限定理来产生高斯噪声。 分析所产生的均匀分布和高斯分布随机信号的均值、方差、自相关等数字特征，估计其概率密度函数并进行分析，估计其功率谱密度并进行分析。说明该高斯噪声是否符合白噪声特性。 对该高斯噪声进行FIR低通滤波，估计输出低通型限带白噪声的功率谱、相关时间等，并结合白噪声通过线性系统相关理论来进行分析。 (According to the theory of pseudo-random sequence, a uniformly distributed random numbers by mixed congruential method to generate Gaussian noise, and then according to the central limit theorem. Produce a uniform distribution of the analysis and the mean of the Gaussian distribution random signals, variance, since the digital characteristics of the correlation, the probability density function is estimated and analyzed, it is estimated that its power spectral density, and analyzed. The Gaussian noise is in line with the characteristics of white noise. FIR low pass filter of the Gaussian noise, the estimated output of low-pass type band-limited white noise power spectrum, time, etc., combined with the white noise to be analyzed by linear system theory.)

实现短时傅里叶变换的功能。分为两种方式：1、matlab自带函数；2、自行编写程序。自行编写的程序效果更加，绘制时频分布图更清晰准确。（附带几篇参考文章）(Short time Fourier transform. Divided into two ways: 1 matlab own function own programming. Write your own program was more plotted frequency distribution more clearly and accurately. (With several reference articles))

When I first studied Kalman filtering, I saw many advanced signal processing submissions here at the MATLAB Central File exchange, but I didn t see a heavily commented, basic Kalman filter present to allow someone new to Kalman filters to learn about creating them. So, a year later, I ve written a very simple, heavily commented discrete filter.

说明：  这个模型可以在MATLAB中计算资金的贬值情况，根据利率与时间的长度，最后得到资金的现值或终值( For example, the cost of an asset is $13,000 with a life of 10 years. The salvage value of the asset is $1000. To find the remaining depreciable value after 6 years, use the following commands. Find the accumulated depreciation with the straight-line depreciation function, DEPSTLN. )
