JPEG 仿真 在Matlab7 上运行，效果最佳(The code of JPEG.If some one want using it,please download。)

这个程序使用vc++实现的一个工程，这个工程的作用就是完整实现了MATLAB和vc++混合编程的关键函数的功能-mexfunction。有其详细的开源代码！(This program uses the vc++ implementation of a project, the role of this project is to complete implementation of the MATLAB and vc++ mixed programming function of the key functions-mexfunction. Has its open source code in detail!)

可以实现快速傅里叶的计算，适用于matlab环境(Calculation can achieve fast Fourier for matlab environment)
