kd-tree 是广泛用来处理多维寻找最近点的数据结构。该文件中是由matlab调用c++代码实现的，其中实现包括kd-tree的建立最近点的查找等。(kd-tree is kind of data structure which is widely used to find the nearest point in multi-demensions.The zip file contain matlab and cpp files.The functions implemented include kd-tree building and nearest points searching and so on.)

自己编的闻邦椿书上的Riccati求转子临界转速，转子为单跨双转盘。有去除奇点，提取振型，收敛迭代为弦截法。有各向异性求取临界转速部分，不过结果可能不准确。(Riccati Wen Bangchun own series of books on demand critical speed rotor, the rotor is a single span double turntable. There are singular point removal, extraction modes, the convergence of iterations for the Secant method. Anisotropy strike critical speed section, but the results may be inaccurate.)

matlab基本实验程序，并行计算编程基本程序(matlab basic experimental procedures, the basic procedures for programming parallel computing)

说明：  用matlab实现的GSM TCH/EFS系统在高斯信道、瑞利信道下的性能仿真，其中用到了循环编码、卷积码、交织码等信道编码技术(Using matlab to achieve GSM TCH/EFS system in the Gaussian channel, Rayleigh channel the performance of simulation, which uses a loop encoding, convolutional codes, interleaving codes channel coding techniques)

计算了贝塞尔函数的一阶导数的零点。 更新BessDerivZerosBisect.m这些变化： 1。允许对m= 0 2。允许用户指定特定的m和k值理想。 3。允许公差输入参数 4。使用一个表的查找能为m和k的小值接近初始化 5。添加错误检查 6。计算衍生w.r.t.以X而不是w.r.t.米（虽然老方法的工作也。）(Calculates the zeros of the first derivatives of Bessel function. Updates BessDerivZerosBisect.m with these changes: 1. Allows for m = 0 2. Allow the user to specify the particular m and k values desired. 3. Allows for a tolerance input parameter 4. Uses a table look-up to get closer initializations for small values of m and k. 5. Adds error checking 6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))

MIMO系统中4发送4接收的最大似然检测算法，可自行扩展到其他发送结构(MIMO systems send four received the maximum likelihood detection algorithm, they are free to expand to other transmit architecture)

Matlab的MPEG程序. 它是MPEG心理声学模型的MatLab实现。(Matlab Program of MPEG. This is an implementation of the MPEG psychoacoustic model 1, layer I, for MATLAB.)
