2010年中兴捧月杯程序设计大赛关于电路的一道编程题的代码(ZTE holding cup 2010 Programming Contest on the circuit of a programming problem on the code)

此程序主要是用Matlab模拟了鱼群算法寻优的过程，对算法寻优的应用有指导作用。(The procedure is used Matlab simulation of fish swarm algorithm optimization process, the application of the algorithm optimization of a guiding role.)

罚函数法是将有约束最优化问题转化为求解无约束最优化问题。在此给出罚函数法的Matlab源程序。(Penalty function method is a constrained optimization problem into solving unconstrained optimization problems. This gives the penalty function in Matlab source.)

PSO算法应用到图像三阈值分割，评价函数为二维最大熵(PSO algorithm is applied to image three threshold segmentation, the evaluation function for the two-dimensional maximum entropy)

星形16QAM的编码与解码，主要是进码流进行编码，加噪声，显示画图，最后解码(Star 16QAM encoding and decoding, encoding and decoding of the star 16QAM star 16QAM encoding and decoding, encoding and decoding of the star 16QAM, star 16QAM encoding and decoding,)

自适应,SER序贯回归算法,权的迭代及画图(dsp，SER)

相场模拟晶枝生长，采用有限差分法计算，可更改参数获得不同结果(Phase field simulated dendrite growth)

matlab下实现降噪，功率谱计算。％程序中设定采样点数为256个，采样频率为10000hz， ％输入信号为随机噪声和两个正弦的合成信号 ％设定的滤波器的截止频率为3500hz ％通过挈比雪肤滤波器，运行程序，比较滤波前后的频域波形 ％滤波去除了高频信号(matlab achieve noise reduction, power spectrum calculation. Sampling procedure set for 256 points, the sampling frequency of 10000hz, input signal for the random noise and the two sinusoidal signals synthetic filter set a cut-off frequency 3500hz manner than through the filter雪肤, run procedures, compared before and after filtering in frequency domain waveforms filtering in addition to high-frequency signals)
