AC97的协议介绍，对正在写相关论文的同学可能有一定帮助！希望大家喜欢，谢谢大家！(AC97 protocol introduced, the students are writing related papers may have some help! Hope you like, thank you!)

学习使用matlab软件，并使用matlab软件编写相应的程序完成对图像的增强处理掌握matlab软件在图像增强技术的处理方法(Learning to use matlab software matlab software to write the program completed master matlab software for image enhancement in image enhancement technology approach)

kd树的实现，用到matlab(kd tree realization used Matlab)

Simulink Model of Buck Converter, Use it with any Motor.

针对均匀线形阵列的阵列波束综合问题，并把这一问题描述成一个凸优化问题。针对更普适的情况。 (For array pattern synthesis problem, and describe it as a convex optimization problem.)

说明：  SVM 现在主要用于故障诊断。他可以解决非线性，小样本。(svm is a means for fault detect.)

说明：  数学建模的常用算法，包括源代码，是我在建模过程中精心筛选的，希望对大家有所帮助(Mathematical modeling of the commonly used algorithms, including source code, which I carefully screened in the modeling process, and hope to be helpful)

由于非线性光学中计算非线性折射系数的数值模拟(as calculated nonlinear optical nonlinear refractive index of numerical simulation)

特征空间方法是现代谱估计的重要方法之一。针对噪声中的复正弦信号的模型，通过特征矢量的方法进行信号空间的分解。通过将信号空间分解为谐波信号空间和噪声信号空间这两个相互正交的空间的方法进行谱估计。Pisarenko,Music,ESPRIT算法都是这一类方法的重要算法。我们通过对不同算法进行比较分析不同算法在各种状况下的表现性能。并针对ESPRIT算法的各种改性和提升进行对比和测试。(Feature space is one of the modern spectral estimation method. Complex sinusoidal signal for the noise model, by the method of the feature vector for the decomposition of the signal space. By decomposition of the signal space to the space harmonic signal and the noise signal space, the method of the two mutually orthogonal spatial spectrum estimation. Pisarenko, MUSIC, ESPRIT algorithm is an important algorithm of this type of method. Different algorithms, our comparative analysis of the performance of different algorithms performance under a variety of conditions. And for a variety of modification and upgrading of the ESPRIT algorithm to compare and test.)
