When you use the Microsoft Automation functions VariantTimeToSystemTime to convert variant time to system time and the SystemTimeToVariantTime to convert system time to variant time, the milliseconds value appears as zero or is ignored

说明：  一个高阶系统转换为状态空间的matlab算法，附有原理(A high-end system into a state space matlab algorithm, with a principle)

说明：  这个程序可以计算线性系统的计算的群延时.(this procedure can be calculated linear system of calculating the group delay.)

非负矩阵分解的一种新方法——Nesterov法，这种方法提出不久，实现的结果很不错(NMF is a new method--Nesterov method, this method is presented shortly to achieve very good results)

这是大学毕业时设计的失真度检测仪论文，由模拟陷波器实现的剔除几波，如果改进的话，可以用数字滤波器实现，不过成本更高(It is designed for university graduation thesis distortion detector by analog notch filter removed to achieve a few waves, if improved, you can use digital filters to achieve, but higher costs)

说明：  包含前馈与串级控制系统和前馈与反馈控制系统两个模型(Including feedforward and cascade control system and the feedforward and feedback control system the two models)

数学实验中用matlab对美国人口进行的仿真和分析(Using matlab mathematical experiment of the United States population simulation and analysis)

matlab常用函数源代码，如sigmerge等函数，可直接调用，代码均通过测试(commonly used functions of matlab source code, such as sigmerge function can be called directly, the code are tested)
