ekf,扩展卡尔曼滤波，组合导航技术，是适合初级学习的资料(ekf，extended kalman filter，integrated navigation)

2D和3D在PML边界条件下的FDTD例子(The example of 2 d and 3 d of FDTD in PML boundary condition)

灰色预测gm（1-1）算法，用于短期时间序列预测，包含残差检验等各种必要检验(Gray predicted all the necessary inspection gm (1-1) algorithm for short-term time series prediction, including residuals inspection)

魔方还原程序,主函数为Cube,采用CFOP，还原步骤为88步左右，底面十字未优化；采用留个3*3矩阵，前面为froo（数字3），后面为baa（数字-3），左面为leff（数字-2），右面为rigg（数字2），上面为upp（数字0），下面为doo（数字1），(Cube restore process, the main function of Cube, using CFOP, the reduction step is 88 steps or so, the bottom cross unoptimized adopt leave a 3* 3 matrix, in front of froo (figure 3), followed by the baa (figure-3), left the leff (digital-2), the right of rigg (figure 2), at the upp (number 0), following the doo (figure 1),)

MATLAB三维显示地震数据, 开放小工具。 这个开放MABLAB三维绘图小工具, 非常好用, 可进行SLICE, CONTOUR, 等交互功能. (MATLAB display three-dimensional seismic data, open the gadget. An open three-dimensional graphics MABLAB gadget, very easy to use, it can conduct SLICE, CONTOUR, and other interactive features.)

Linear prediction follows naturally from the general mathematics of linear systems. As the system output is defined as a linear combination of past samples, the system’s future output can be predicted if the scaling coefficients bj and ak are known.

说明：  本人经过对最小二乘法拟合程序进行了归纳汇总编写了这个MATLAB小程序，一般情况都适用。(General least squares fitting procedure code)

小世界模型 近日需要用到无标度网络与小世界网络，早上用matlab写了这两种网络的matlab程序，放在这，有用者可以拿去用，请自己验证正确性后使用。 (Small-world model)
