定义一个结构体变量（包括年、月、日），计算该日在本年中为第几天？（注意考虑闰年问题），要求写一个函数days，实现上面的计算。由主函数将年月日传递给days函数，计算后将日子传递回主函数输出(Define a structure variable (including the year, month, day), calculated on that day in the middle of this year for the first few days? (Note that the leap to consider the issue), asked to write a function of days, to achieve the above calculations. By the main function will be passed to the days date function to calculate the days will pass back to the main function of the output)

基于matlab平台，通过DCT算法来对视频进行压缩。代码包括视频分解成帧，DCT算法压缩，帧合成视频，以及综合的视频压缩M文件，可以直接仿真。有相应的图片，以及压缩前后的视频，还有原理word报告。(Based on matlab platform, through DCT algorithm to compress the video. Code includes video decomposition framing, DCT compression algorithm, frame composite video, and integrated video compression M files can be directly simulated. Corresponding images, and compressed video before and after, as well as the principle of word report.)

本程序可以实现对图像用Matlab进行奇异值分解(This program enables the images to use Matlab the singular value decomposition)
