采用仿真实验的方法，分析和评价FCFS、SJF、RR和MLFS算法的优劣，用c++实现四种调度算法，源代码如下，思路程序内有注解(Method using simulation, analysis and evaluation of FCFS, SJF, RR, and MLFS merits of the algorithm, using c++ to achieve the four scheduling algorithms, source code is as follows, ideas, comments within the program)

Calculation of diffraction efficiency of rectangular phase grating (scalar theory)

EIGENFREQ finds an approximation for the eigenfrequency of the resonator within a range and at a resolution specified by the user. The user specifies the range in terms of the minimum and maximum values of each of the real part and the imaginary part of frequency, and the user specifies the resolution in terms of the number of evenly-spaced real frequencies and complex frequencies at which EIGENFREQ is to performcalculations.

LZ复杂度反映的是一个时间序列中，模式数量序列长度增加的速率。为了在计算机上对连续信号的复杂度进行计算，需要先将连续信号离散化，通过预处理后的心音信号符合这个要求。实现心音信号的分离(LZ complexity reflects a time series model number sequence length to increase the rate. For a continuous signal on the computer, the complexity of the calculation, you need to first discretize the continuous signal by pretreatment of the heart sound signals meet this requirement. To achieve the separation of heart sound signals)

50HZ陷波器的开发，开发环境为matlab。适合做课程设计。(The 50HZ notch developers, development environment for matlab. Suitable for curriculum design.)

基于养老保险原理对养老保险抚养比进行测算，得出我国养老保险抚养比大小。(Based on the principle of old-age insurance pension dependency ratio is calculated on, come to the size of China' s pension dependency ratio.)

给学计算机接口与控制的同学发福利了，一些简单易实现的pid控制源码，直接在matlab上就可以跑起来(To learn computer interface and control the welfare of the students sent some simple and easy to achieve pid control source, directly in matlab can run up)

利用matlab的lpc function 實做出將input source音檔算出其coefficent and gain並由上述資料可以重新合成還原音訊(The lpc function using matlab real audio file to make the input source is calculated by its coefficent and gain reduction above information can be re-synthesized audio)
