很好的FEM（有限元）matlab工具包(good FEM (Finite Element) Matlab Kit)

JPEG连续色调静止图像无损压缩的最新标准JPEG LS的C语言实现，还带有一个很友好的图形用户界面，那些学习图像编码的工程师可以参考一下这个实现的源代码。(JPEG continuous tone still images of the latest standard lossless compression JPEG LS realize the C language, but also with a very friendly graphical user interface, those who study and image coding engineers can refer to this realization of the source code.)

这是《通信原理matlab仿真教程》所对应的电子教案，里面有每张例题对应的源程序代码。。。(This is the " communication theory matlab simulation tutorial" corresponding to the electronic lesson plans, there are examples of each corresponding source code. . .)

Active Contour using matlab

此源代码,是一个非常适合研究与学习用的电力系统仿真软件源码，是一种基于mattlab的，有非常好的界面、仿真库等等，能进行PF、CPF、OPF等一些计算。 (This source code is a very suitable for research and study used in power system simulation software source code is a matlab-based, and has very nice interface, the simulation database and so on, can P )

说明：  神经网络编码源程序，可以调用，方便使用，可进行二次开发(neural network source code can be called, for ease of use, can be re-developed.)

This model gives you the transformation of abc components of voltage and current into dqo components which is mostly used in power systems and power electronics

1. 给一段原始的语音信号（可以是自己录制的一段语音），加上一频率为3.8kHz的高频余弦噪声和频率为3.6kHz的高频正弦噪声（幅度自己可以选择），用窗函数设计一滤波器（要求最小阻带衰减为50dB）对加噪后的语音信号进行滤波，画出滤波器的频率响应曲线，画出滤波前后的时域图和频谱图。 需要用到的函数： fir1 用窗函数设计FIR滤波器的函数 2. 用GUI设计一界面（如图1所示）完成如下功能： 1） 输入一语音信号，画出语音信号的时域图和频谱图； 2） 对语音信号加噪处理，画出加噪后的时域图和频谱图； 3） 给定滤波器的性能指标，采用几种不同的方法设计滤波器对加噪信后进行滤波，画出各滤波器的频率响应曲线，画出滤波后的时域图和频谱图。 (1. to some of the original speech signal (which can be a voice you record yourself), plus a cosine frequency of 3.8kHz frequency noise and frequency of 3.6kHz frequency sinusoidal noise (in the range that they can choose), with a window function to design a filter (requires a minimum stop band attenuation is 50dB) after adding noise to the speech signal is filtered, the filter frequency response curve to draw, draw diagrams and time-domain spectrum before and after filtering. Need to use the function: function fir1 with window function design FIR filter design 2. Using a GUI interface (Figure 1) complete the following functions: 1) an input speech signal, the speech signal in the time domain to draw graphs and spectrum 2) adding noise to the speech signal processing, draw diagrams and time-domain plus noise spectrum after 3) to set the filter performance, using several different methods designed to filter letter after adding noise filtering, draw the frequency response curve of each )
