由1790-1980年间美国每隔十年的人口记录表为基础进行分析。(Exponential growth model of population )

基于MATLAB的2FSK信号产生于处理，这个程序比较好，希望对大家有用(Based on MATLAB 2FSK signal processing, this program better, we want to)

采用matlab编程，实现克里金差值算法(Using matlab programming, the difference between the kriging algorithm)

A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.

以上为matlab在控制系统仿真中一些例子程序，对学习控制系统仿真的朋友有一些帮助(About mathematical modeling risk overdraw problem program, mainly to solve the risk of the investment in the optimal strategy is more than the main Linux multi-threading with processes the correlative analysis of the performance, very classic, is suitable for various beginners above for matlab in control system simulation program some examples to the study of control system simulation friend has some help )

Gabor小波变换与PCA的人脸识别代码，基于K均值的PSO聚类算法,使用大量的有限元法求解偏微分方程。( Gabor wavelet transform and PCA face recognition code, K-means clustering algorithm based on the PSO, Using a large number of finite element method to solve partial differential equations.)

已知一个序列x(n)=0.5cos(0.55*pi*n)+cos(0.45*pi*n),时域FFT分析其频谱。 （1）使用不同宽度的矩形窗截断该序列为M点，取M分别为：20，40，160,观察不同长度对频谱影响；（2）使用哈明窗和凯泽窗重做；（3）对三种窗的结果进行分析比较；（4）总结窗类型和长度对频谱分析的影响。 (Known a sequence x (n) = 0.5cos (0.55* pi* n)+ Cos (0.45* pi* n), time-domain FFT analysis of its spectrum. (1) use a different width of the rectangular window of the sequence for M cut-off point, take M are as follows: 20,40,160, observing the impact of different lengths of the spectrum (2) the use of Hamming window and the Kaiser window redo (3 ) on the three windows analyzed and compared the results (4) summarize the type and length of window for spectrum analysis.)

GUI basedforms buttons and actions to be developed in matlab.. In this file i can add some extra functionality of the user friendly functionality.
