有用的MATLAB小程序，和大家交流一下，下网在这里可以学到很多(useful)

用matlab仿真的离散信号的频域实验分析(Experimental analysis of the frequency domain of the discrete signal simulation using matlab)

说明：  matlab科学计算的几乎所有数学算法以及仿真。每一个m文件在我学习的时候都验证了其正确性。前面的比较简单，逐步深入。另外对部分算法本人在学习中做了优化，更简洁。(matlab scientific computing almost all mathematical algorithms and simulation. M each file in my learning at all times to verify its correctness. In front of a relatively simple step by step in depth. In addition to some algorithm I have done a study of optimization, a more concise.)

样条插值的相关matlab源码，包含6个.m的文件(Spline interpolation matlab source code, containing 6 m files)

获取和设置文件或文件夹得创建、读取及修改信息。(Get and set the times for creation, access and modification of a file or folder (Windows only))
