教你怎样吹笛子：详细介绍了竹笛的基本吹奏法和详细技巧，内有五十首练习曲，李小逸编著 (Teach you how to play the flute: flute introduces the basic skills of playing methods and detailed, the Fifty Etudes, Li Xiaoyi ed)

提出了一个混沌系统,并对该系统的基本动力学特性进行了深入研究.得到该系统的Lyapunov指数、Lyapunov 维数,给出了Poincaré映射图以及时域图和相图.运用电子工作平台EWB软件对实现该新混沌系统的振荡器电路进行了仿真实验.经过数值仿真和电路系统仿真证实该系统与以往发现的混沌吸引子并不拓扑等价,属于新的混沌系统.(Presents a chaotic system, and the basic dynamic characteristics of the system were studied. Get Lyapunov exponent of the system, Lyapunov dimension, given the Poincar maps and graphs and time-domain phase diagram using electronic work platform EWB software for implementing the new chaotic system oscillator circuit simulation experiments through numerical simulation and circuit and system simulation confirmed that the system ever discovered chaotic attractor is not topologically equivalent, is the new chaotic system.)

This is a MATLAB implementation of the SIFT keypoint detector and descriptor (do_gaussian: generate Gaussian scale space of input image do_diffofg: generate Difference of Gaussian (DoG) scale space do_localmax: local extrema as the potential keypoints do_extrefine: refine the keypoints by discarding the ones with low contrast and along an edge do_orientation: compute the orientation of a support region of keypoint do_descriptor: compute the descriptor of a keypoint based on image gradients. do_match: match two images based on the nearest neighbor principle and spatial consistency. do_sift: generate the SIFT descriptors for a given input image. It basically s all the functions above. )
