Amplify and Forward matlab code

Here s the code! Too many people ask for this Using this code you can save an image item as a jpeg image, specifying the quality of it. Jpeg quality is the same as compression so the lower the quality, the smaller the file size. It s simple to use(Here's the code!

文章讨论了多变量灰色预测模型的算法, 给出多变量灰色预测模型的Matlab 程序. 通过实例说明算法程序的应 用和效果(This paper discusses multi-variable gray prediction model algorithm, given multivariable gray forecasting model of Matlab procedures. Algorithm by examples of their application and effectiveness)

利用Matlab软件编程实现DDS（直接数字频率合成技术）。设时钟的频率为固定值f_C，在CLK的作用下，如果按照0000,0001,0010，…，1111的地址顺序读出ROM中的数据，即表1中的幅值编码，其正弦信号频率为f_01；如果每隔一个地址读一次数据（即按0000,0001,0100，…，1110顺序），其输出信号频率为f_02，且f_02将比f_01提高一倍，即f_02=2f_01；其余类推。这样，就可以实现直接数字频率合成器的输出频率的调节。(Matlab software programming DDS (direct digital frequency synthesis). Clock frequency set to a fixed value f_C, under the effect of CLK, according to 0000,, ..., 1111 of the sequence of addresses in the ROM reads the data, i.e., the amplitude of the encoding in Table 1, the frequency of the sinusoidal signal f_01 if every time a read address data (ie 0000,0001,0100, ..., the order of 1110), the output signal frequency is f_02, and f_02 f_01 than doubled, i.e. f_02 = 2f_01 rest on. This allows direct digital frequency synthesizer output frequency regulation.)
