使用有限时间差分算法来计算2维目标散射的例子(use of the limited time-difference algorithm to calculate two-dimensional scattering example)

用于指纹图象的归一化,和二值化处理,具有很好的效果(The normalization and binaryzation processing in the fingerprint image ,the result is good.)

fem for computational electromagnetics

控制问题转化为了数学规划问题。推导出目标函数对于待求参数的梯度公式，并利用序列二次规划算法求出最优控制量(the problem is changed into mathematical programming problem and formulae are derived for computing the gradients, also, a computational method for finding the optimal control is obtained by using the Sequential Quadratic Programming (SQP) algorithm.)

蚂蚁算法求解TSP 很不错的 Matlab程序(ant colony optimization FOR TSP)

此程序演示了如何在Matlab中调用Fortran77编写的函数，包含参数虚实结合应该注意的问题。(illustrate how a MATLAB program can call a FORTRAN77 function, passing data to the function, and receiving results from the FORTRAN77 function.)

caesar加密算法,可用于简单加密或实验(encryption algorithm)

说明：  该程序用来读取地震原始资料segy格式的数据，也可以增加些模块对数据进行处理(The program used to read raw data segy seismic data format can also be added so that the data processing module)

filtering with kalman

doarima.m MATLAB script to do an ARIMA(p,d,q) analysis where d is set but P and q can be vectors of values you want to try. It produces AIC and FPE (final prediction error) values for comparing models. The AIC is different than the one computed by S+, but they both minimize on the same model for the arma22.dat simulated data.
