很好很实用的matlab工具函数包括:绘图的相关问题的函数(Nice and useful tool matlab functions include: issues related to the function of drawing)

利用小波进行图像压缩，使用的是一代小波对图像进行的压缩(image compress using wavelet)

该模型是模拟信号数字传输系统，可以把一个模拟信号通过PCM编码译码，信道2FSK编码译码，再通过一个二进制对称信道，可以恢复出原模拟信号(The model is the analog signal digital transmission system, an analog signal by the PCM codec, channel 2FSK codec, and then through a binary symmetric channel, you can restore the original analog signal)

编程实现State-Space对应功能，同一个输入在一个s函数和一个相同的传函下所得到的输出是相同的(State-Space corresponding programming function, the same input in a s the same function, and a transfer function of the resulting output is the same)

EMD和EEMD变换在信号去噪中的应用（含EEMD程序）(EMD and EEMD transform in signal denoising (including EEMD program))

高斯二维滤波器设计，以及中值滤波等一些matlab程序，方便使用。(Two-dimensional Gaussian filter design, as well as median filtering and some matlab program, easy to use.)

Power Flow Sistema de 4 Barras

this code to generate parity check matrix of Low density parity check cod, and encode in order to codeword

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)
