matlab曲线拟合工具箱使用说明，可以直接得到拟合曲线的表达式。(matlab_curve)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)

说明：  混沌永磁同步电动机混沌模型的Lyapunov指数计算程序 (chao bhhb)

matlab的S-function函数的写法(the wording of the S-function function matlab)

matlab实现的各种数字滤波器，包括矩形窗，汉明窗，汉宁窗，kaiser窗等。(matlab digital filter to achieve a variety of, including the rectangular window, Hamming window, Hanning window, kaiser windows.)

说明：  讲解berkley套接字的详细知识，并结合有详细的例子对套接字的应用做了充分阐释(Detailed knowledge to explain berkley sockets, combined with detailed examples of the application of the socket to do a full explanation)

很好的EKF算例，自己写的哦，计算结果跟matlab工具箱计算结果一样(good code for EKF)

matlab中实现直方图均衡化，图像必须是灰度图像，真彩色要转化为灰度图才能正确处理。(matlab histogram equalization, the image must be grayscale images, true color to be converted to grayscale to be processed correctly.)

matlab GUI设计，内容全面，通俗易懂，(matlab GUI design, comprehensive, easy to understand,)

基于IDCT_DCT域的全相位数字滤波和图像内插_赵黎丽,很不错(All phase digital filtering and image in IDCT_DCT domain based on Zhao Lili interpolation _)
