寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

关于主元分析的简单的小程序。适用于初学者。(Simple program about PCA. Suitable for beginners.)

格式 [sqnr,a_quan,code]=u_pcm(a,n) 输入样值序列a 、量化电平数目n, 程序计算量化间隔、进行均匀量化、进行编码、计算量化信噪比， 返回量化信噪比squn、编码前的量化序列a_quan、编码后的码序列code。 (Format [sqnr, a_quan, code] = u_pcm (a, n) input sample value sequence a, the number of quantization levels n, the calculation procedures to quantify interval, the uniform quantization, coding, computing quantization noise ratio, return quantization noise ratio squn, to quantify the pre-coding sequence a_quan, coding sequences after the code.)

DNAtranslator 是一个用于将DNA 序列转换成相对于他的蛋白质序列的一个方程。这是本方程的代码。(DNAtranslator is a small function to convert a DNA sequence into the correspondent protein sequence.)

说明：  绝对原创的matlab 量子免疫遗传算法。改程序功能是实现求一个函数的最小值。可运行 (又发一遍，说我格式不对，不知有没有成功)(matalab QGA.)
