Signal and Systems Project in MATLAB code

利用matlab编写的遗传算法程序，很经典，是从一个毕业的师姐那要过来的，跟大家分享一下(Prepared using matlab genetic algorithm, very classic, is a graduate of the senior sister apprentice that to come and share with you)

It is a matlab code for detecting brain tumor in MR images using CIELAB color space model segmentation.

说明：  K-SVD算法程序，利用聚类算法对字典进行训练(K-SVD algorithm program, the use of clustering algorithm is trained on a dictionary)

说明：  shtXX 实际应用样例，有详细中文说明，已经调试验证过(shtXX the practical application of the sample, a detailed explanation in Chinese, has been verified debugging)

说明：  我的matlab学习就是从本书开始，他适合初学者，可以快速带你进入matlab应用(My study is from the book to start matlab, he suitable for beginners, you can quickly take you into the matlab application)

这是一本学习matlab simulink方面实例的书，通过不断地练习例子，可以很快的进入入门阶段。(this is a book of matlab simulink,we can study well matlab simulink through the book.)

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.)

2D FFT的源代码，图形显示变换结果，关键代码有详细注释(2D FFT source code)

求两个数组的和差积商，其主要功能就是计算两个数组的和差积商(Find difference between two arrays and product providers)
