数学建模中某些算法的解法,关于数学模型第三版姜起源 谢金星等的作品。。。。。(some solutions about matlab.)

this is water mark code

说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

ARIMA建模，主要包括平稳化、模式识别、模型定阶几个步骤(ARIMA modeling, including smoothing, pattern recognition, model order several steps)

设计单级倒立摆的品级模糊控制器。运用串级模糊控制器控制单级倒立摆，内环模糊控制器控制角度，外环模糊控制器控制位移，运用种群遗传算法优化两个模糊控制器的参数。(Grade of single-stage inverted pendulum fuzzy controller is designed.Cascade fuzzy controller is used to control a single inverted pendulum, the inner ring control Angle of the fuzzy controller, the outer ring control displacement of the fuzzy controller, the use of two population genetic algorithm to optimize fuzzy controller parameters.)

PanCOS/PSAM 技术参考手册,对PSAM编程特别有用(PanCOS/PSAM technical reference manual, programming is particularly useful on the PSAM)

说明：  采用频率调制 为1000Ｈｚ的载波，在解调前把加性白高斯噪声加入到调制信号。当噪声功率和调制信号功率比为０.００１，０.０１，０.０５，０.１和０.３是进行解调并绘出调制信号(The use of frequency modulation for the 1000Hz carrier, in the demodulation before AWGN added to the modulation signal. When the noise power and modulation signal power ratio of 0.3 is 0.001,0.01,0.05,0.1 and demodulation and modulation signals mapped)

说明：  模式识别，线性分类器，经调试可用。希望能帮到需要的人。(Pattern recognition, linear classifier, debugging is available. I hope to help people in need.)
