基于curvelet的灰度图像增强，是在变换域里通过修改系数等达到(Curvelet-based gray-scale image enhancement, in the transform domain to achieve by modifying the coefficient)

说明：  Matlab程序；关于图像压缩；基于小波变换分析与应用(Matlab program on image compression Analysis and Application Based on Wavelet Transform)

一个信号通过均匀圆阵的DOA估计，估计了方位角和仰角，并利用三维图形展示。(A signal through a uniform circular array DOA estimation, it is estimated that the azimuth and elevation, and the use of three-dimensional graphics display.)

discuss the cooling of a circular fin by means of convective heat transfer along its length. Convection gives rise to a temperature-dependent heat loss or sink term in the governing equation. Shown in Figure 4.9 is a cylindrical fin with uniform crosssectional area A. The base is at a temperature of 100°C (TB) and the end is insulated. The fin is exposed to an ambient temperature of 20°C

这是一个无线通信中最常应用的直接序列扩频的程序(direct spread spectrum)

基于matlab对语音进行特征参数提取，毕业论文等神器，用处很大(Based on matlab voice characteristic parameter extraction, thesis artifact, useful)

用MATLAB对微带贴片天线进行仿真，出来S曲线图(Using MATLAB simulation of microstrip patch antenna, out of S curve)

振动消噪代码，包括白噪声、有色噪声、粉色噪声的生成；相关系数法消噪、小波软阈值消噪、互相关系数消噪三种方法对比。(Gaussian white noise, Gaussian colored noise and pink noise have been processed to verify the validity of the algorithm. we also compared the proposed method with the correlation coefficient method and wavelet soft threshold noise reduction methods. the results show that the proposed method can be performed on a variety of signal noise reduction, which is better than the correlation coefficient method and wavelet soft threshold noise reduction methods.)

有关支持向量机的优化算法，可是支持向量机提高准确率及速度(About the support vector machine optimization algorithm, but support vector machine to improve the accuracy and speed)
