k-d树的matlab程序，包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo scripts(kdtree_demo.m & kdrange_demo.m),很实用( This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions. Included are the source code files in kdtree/src, as well as precompiled mex files for the following systems: - Mac OS X (Matlab 6.5) - Redhat Linux (Matlab 6.5) - Windows (Matlab 6.1) Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m). The new features added June 2004: + You can now use N dimensional data points, where N>3. + Use KDTREEIND to return the index value to the closest point, instead of the closest point values. + KDRANGEQUERY can now return these index values as well.

随机信号功率谱估计 非常好 希望能够帮助大家(Random signal power spectrum estimation Very good hope to help everyone)

IFS,平移，旋转的，非常简洁，可以迅速的带入数据，即可出现图像(IFS, translation, rotation, and very simple)

画duffing方程的相图，不能保证正确，请大家斟酌使用。欢迎交流。(The phase diagram drawn duffing equation, can not guarantee correct, please use discretion. Welcome to exchange.)

单自由度振动系统－－基于MATLAB建模仿真。根据单自由度振动系统数学模型,设计了单自由度振动系统的数学仿真实验,实验结果给出了振动方程的数值解,并用几何方式定量描述了振动过程和频幅特性.(single-freedom vibration systems-- based on MATLAB simulation modeling. Under the single-freedom vibration systems mathematical model, the design of single-freedom vibration systems of mathematical simulation, The experimental results are given vibration Numerical Solution of equation, and using quantitative description of the geometric means of vibration and frequency properties.)
