直方图均衡化的另一种解法，不是用累加的方法得到的，是用分配灰度值空间的办法。(Histogram equalization another solution, instead of using the cumulative method is the use of the distribution of gray value space approach.)

实验结果表明该算法对非冲击噪声效果良好。 lx_main为主程序，NS_lxwz为噪声估计模块，lxG_wz为增益估计模块，noise_sound为测试用含噪语音。 算法原理参见本人的文章《一种引入延迟的语音增强算法》。(Experimental results show that the algorithm for non-impulsive noise effect is good. lx_main the main program, NS_lxwz for the noise estimation module, lxG_wz for the gain estimation module, noise_sound to test the noisy speech. Algorithm theory see my article " delay the introduction of a speech enhancement algorithm." )

this code helps to understance DSSS direct seq. spread spectrum. in comm.

说明：  声品质中的响度，尖锐度，粗糙度以及起伏度四种声品质参数计算matlab例子编程(he calculation of loudness, sharpness, roughness and undulation in sound quality by MATLAB)

用simulink做的模糊PID控制，里面包括了3个模型，每个模型的fuzzy控制模块都是通用的。(To do with simulink fuzzy PID control, which includes three models, each model of the fuzzy control module are generic.)

用matlabe对于sobel算子，进行模式实现，能取得明显的边缘检测效果！(Matlabe for using sobel operator, to carry out mode, can achieve a clear effect of edge detection!)

对接收到的磁场信号进行低通滤波，去除高频噪声(Docking of the magnetic field signal received by low-pass filter to remove high frequency noise)

特殊随机矩阵的生成，包含两个程序，一个可以随机生成行和和列和均为K的0-1矩阵，另一个可以随机生成稀疏矩阵。(Matrix generation,concluding two program,one can generate the 0-1 matrix that have the same row sum and column sum,the other can generate sparce matrix.)

主成分分析算法（PCA），这是一个外国人编写的，很具有参考价值(principal component analysis algorithm (PCA), which was prepared by a foreigner, it is very valuable reference)
