一个检测ARMA的matlab程序，可以显示p,q的值( a test program to calculate the parameters of ARMA)

1、利用自相关法找出含有大量数据的周期信号的周期 2、利用互相关对齐含有大量数据的多路采样信号以便分析 3、使用分段平滑经过求导后的含有干扰的图像曲线(1, using the autocorrelation method contains large amounts of data to identify the period of the periodic signal 2, using the cross-correlation contains a large amount of data aligned with the sampling signal for the multiplexed analysis, the use of segmented through derivative after smoothing with interference by the image curve)

This function computes the backbone structure of a given weigthed graph (Matrix), keeping a minimum min_dens_nc degree for each node.

毕设，圆拟合程序，使用最小二乘法。 输出圆心，半径。(Picasso, circle fitting procedures set, using least-square method. Output circle, radius.)

matlab中采样mp3格式的音频文件的程序，包含注释。(matlab mp3 audio sample rate)

说明：  internal on line partial discharge

direct sequence spread spectrum technology for secure data tranfer

求N个字符的不重复排列数，不是标准的递归写法，供求职时笔试参考。(Seek N-character array of non-repetition number, not an ordinary recursive formulation for the job when the written reference.)

说明：  电力系统中的牛顿拉夫逊算法实现潮流计算，Matlab实现，可以直接读取数据，目前110节点适用(Power System Newton Raphson power flow algorithm, Matlab implementation, you can read the data for the current node 110)

这是一个matlab航天工具包 包括一定的解释说明 很好用 希望对大家有帮助(This is a space Matlab tool kits must include an explanation with good wishes to be helpful)
