Some of the files model satellite formation for a leader and follower configuration while others relate direction cosine transformation for 3-1-3 rotation

本程序可以用来计算太阳能总辐射，晴天模型(simulation the total solar radiation)

matlab在振动分析中的应用源代码 包括各种信号处理的时域频域方法 强烈推荐 仅供学习交流(matlab in vibration analysis application source code, including various signal processing frequency domain method is strongly recommended for learning exchanges)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )
