区块定位内容滑动，scrollTo页面锚点平滑移动插件JQ系列，点击页面中的链接，可控制某区域内的图片或文字内容平滑滚动，挺实用的功能。(Content sliding block positioning, scrollTo page anchor to move smoothly plug JQ series, click on the link in the page, you can control the image or text content within a region smooth scrolling, very useful features.)

这个程序演示了如何应用耦合结构空气动力问题，通过Matlab编程，分析了飞行器机翼颤振等问题。(This model demonstrates how to implement a coupled structural-aerodynamic problem. The wing, otherwise rigid, is allowed to pitch and plunge. The motion of the wing is defined using SimMechanics blocks. The aerodynamic model is a simple, quasi-steady formulation. Dynamic pressure is manipulated by varying the Mach number & Altitude. You can also vary the CG location of the wing by double clicking on the picture of the BACT subsystem. The structural, mass, and aerodynamic properties all come from the following "Modeling the Benchmark Active Control Technology Wind Tunnel Model for Application to Flutter Suppression" by Martin R. Waszak of NASA Langley. Automatic flutter detection is implemented via a state-machine in Stateflow. )

for using this code need to use signal toolbox and general toolbox in your matlab Using Haar transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Haar transform and finding the SNR to see how well decompression works

It shows what a jpeg compression is all about. the function implements the DCT transform, using a matrix operator. note that matlab has a function for the DCT and iDCT transforms that might be more efficient.
