simulink models of different types of motors

基于MATLAB的声音过滤器，可手动对各频段的声音进行过滤选择。(MATLAB-based audio filter that can be manually voices of each band filter options.)

在不同的频率偏移的情况下技术ICI自消除误差仿真(ICI self cancellation error simulation in different frequency offset case technology)

说明：  智能算法三十例，matlab版，希望对大家有用，真心要好好学习一下(this is very good and helpfull to you!)

说明：  该仿真模型是基于matlab的三电平空间矢量整流器，模型由本人自己搭建。运行结果良好。(The simulation model is a three-level space vector rectifier based on matlab.The result is good.)

共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。 在各种优化算法中，共轭梯度法是非常重要的一种。其优点是所需存储量小，具有步收敛性，稳定性高，而且不需要任何外来参数(Conjugate Gradient method (Conjugate Gradient) is between the steepest descent method between Newton method and a method, it only USES a derivative information, but overcome the steepest descent method slow convergence of weakness, but also avoid the Newton law needs to storage and computing Hesse inverse matrix and shortcomings, Conjugate Gradient method is not only solve linear equations with most of the large method, and also one of the most effective solution large nonlinear optimization of one of the algorithm. In all kinds of optimization algorithm, the conjugate gradient method is very important. Its advantage is the storage capacity needed, it has small step convergence, high stability, and doesn t require any exotic parameters numerical experiment, this is the modern scientific computing of the answer above problem sets)

这是国外做得一个课题，后面附有源代码，matlab的代码(This is done abroad, a task attached to the source code, matlab code)

Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function conv2fft performs a 2D FFT-based convolution. Type help conv2fft on MATLAB command window for more informations.
