此程序和fn_DBn_2D程序是一起的，用于测试fn_DBn_2D程序的分解和重构效果，里面用到了一副典型图象：babala。(This procedure and the procedure is fn_DBn_2D together for testing procedures fn_DBn_2D effects of decomposition and reconstruction, which uses a typical image: babala.)

计算机方面的基础知识，对大家应该有所帮助 (Basic knowledge of computers to all of us should be helpful)

过程控制中对于加热炉的前馈控制实现，通过精确的模型可以达到完美的控制效果(process control for the heater feedforward control achieved through precise model can achieve perfect control results)

一个模拟退火算法的例子，程序虽然简单但降温条件，降温函数，内外终止准则都有。可供初学者参考。(Example of a simulated annealing algorithm, the program is simple but cool conditions, cooling function, both inside and outside the termination criterion. Reference for beginners)

在MATLAB环境下实现了CDMA通信系统仿真，程序流程为：随机序列产生--WALSH码扩频--BPSK调制--加入（和不加入）高斯白噪声--BPSK解调--WALSH码解扩，对过程波形进行了存储，对加噪与不加噪情况下的解码结果进行了对比，并绘制出信噪比与误码率关系图。(In the MATLAB environment to achieve a CDMA communication system simulation, the program flow as follows: random sequence generated- WALSH yards Spread Spectrum- BPSK modulation- to join (and not to join) Gaussian white noise- BPSK demodulator- WALSH yards Solution expansion of the process of waveform storage, to add noise and without noise cases, the decoding results were compared, and draw out the signal to noise ratio and bit error rate diagram.)
