灰度图像灰度经过按位混沌加密后再对其混沌置乱变换，阀值判断其迭代次数，达到预期加密效果(After a bit gray gray chaotic encryption by scrambling after its chaotic transformation, determine the threshold number of iterations to achieve the desired effect of encryption)

In this paper we present the usefulness of the algorithm DCT (Discrete cosine Transform) blocks applied level image compression JPEG (Joint Photographic Experts Goup). It has been shown that this algorithm is the most efficient in the case of compression because it has very good properties for compaction energy related values. As a basic principle we eliminate high frequencies and keep the low and medium without visibly affecting image. DCT in JPEG compression algorithm is encountered in practical applications such as face detection, skin color, facial recognition, iris, fingerprints

matlab教程，matlab参考书，学习matlab必备啊！(matlab for study.)

说明：  对于非均匀线型阵列，以降低波束方向图峰值旁瓣为目标，在给定阵元数和阵列孔径的约束条件下，利用多种群并行进化遗传算法进行阵元布阵优化。(For non-uniform linear array, in order to reduce the peak side lobe of beam pattern, the multi population parallel evolutionary genetic algorithm is used to optimize the array element arrangement under the constraint of the number of array elements and array aperture.)

C语言实现弗洛伊德路径搜索，同时为了提供接口，使用命令行方式给出原始矩阵地址，并且也已txt文本形式将结果保存。测试效果：一个需要在MATLAB中运行8秒的矩阵，在使用该程序时，总共只用了5秒（MATLAB初始化数据+调用该程序+该程序运行+返回至MATALB所用的时间）。而在MATLAB中使用该程序与调用函数相差不大。(C language Freud path search, and in order to provide an interface, use the command line gives the address of the original matrix, and also save results in text form txt. Test Results: A need to run 8 seconds in the MATLAB matrix, in the use of the program, a total of only 5 seconds (MATLAB initializing the program+ data+ call+ back to the program running time spent MATALB). In MATLAB, use the program with little difference between calling a function.)

用MATLAB实现fft变换，很easy，源代码如下(MATLAB，fft)

matlab源代码，多目标规划模型的建立与求解，可以解决很多问题(matlab)
