计算水声传播的快速场(FFP)程序，基于传播矩阵，迭代和快速傅里叶变换方法。(underwater acoustic field computing Fast FIELD Program, based on TMM, FFT etc.)

说明：  用于石油地震资料数字处理，包括 地震偏移（二维或三维）、滤波程序、重采样、具有很广的应用前景，还可以移植到其他的工程领域。(oil for digital processing seismic data, including seismic migration (2D or 3D), filtering procedures, re-sampling, have a very broad application prospects, but also can be transferred to other engineering fields.)

说明：  matlab程序，有约束最优化问题直接法--复合形法(matlab program, constrained optimization problems are the direct method- the complex method)

说明：  实现基2时域频域抽取fft算法，可输出运算后所得复序列的模值序列，并可记录显示计算所用时间(Achieve base 2 fft algorithm frequency domain extraction can be obtained after computing the output sequence of modulus of complex sequences can be used in the calculation time, records show)

非定常导热，附件包含3个源代码。分别对应着FTCE、BTCS和紧致格式的程序代码(unsteady conduction)

最小二乘递推算法及其matlab实现（计算估计值）(least squares method)

基于牛拉法的电力系统潮流计算，该程序是计算IEEE3节点的，采用matlab编程(Cattle Rafah-based power system load flow calculation, the program the calculation IEEE3 node, using matlab programming)

说明：  FFT，整型数据代替浮点型数据 本程序是搜集资料并加上自己的分析，整了很长时间才测试通过的FFT程序，运行时间和所占内存方面都比较满意。(FFT, integer data instead of floating point data This program is to collect data and add their own analysis, the FFT program passed the test for a long time, the running time and memory occupied are relatively satisfactory.)

说明：  使用时间序列分析AR方法对油价进行分析，以及预测。采用BIC准则进行判阶，最小二乘法进行参数估计(AR time series analysis using the method of price analysis and forecasting. BIC criteria used sentence order, the least square method for parameter estimation)
