code-4

finding peak or reversing point from up trend to down trend and you can switch to find trough by findpeak(-x)

实际光学元件的畸变波前建立了畸变波前模型,畸变进行了仿真研究,给出了二维平面的matlab源代码(The actual wavefront distortion of optical components to establish a distorted wave-front model, a simulation study of distortion are given two-dimensional plane, the source code matlab)

说明：  详细叙述了MATLAB的基本用法并且有一定的实例可供参考(Described in detail the basic use of MATLAB and some examples for reference)

AIC 系统辨识算法matlab原程序 供大家参考(AIC system identification algorithm matlab program for your reference the original)

求解Ds粒子衰变的手征修正参数,涉及多目标的最优化。(Chiral symmetry-breaking parameters to Ds mesons)

《概率论与数理统计》优秀学习资料，工科数学基础(" Probability and Statistics" excellent learning materials, engineering mathematics)

层次分析模型，可确定权值，将定性转化为定量。神经网络模型、池火灾模型。(analytic hierarchy model，To determine the weights, convert qualitative to quantitative.)

说明：  生成有色噪声，并显示噪声功率谱。这该死的20个字(Generating colored noise)

1、 生成多周期线性调频信号，并对其进行频谱分析； 2、 对仿真生成的信号利用两种窗口函数进行STFT变换生成时频分析图(1, to generate multi-cycle chirp signal, and its spectrum analysis 2, the signal generated by the simulation window function using two STFT transform to generate time-frequency analysis chart)

说明：  非均匀有理B样条的matlab程序，其中用到了C的混合编程。对于学习数据融合技术的人很有帮助！(Non-uniform rational B-spline matlab program, which uses a mixture of C programming. Data fusion technology for the study of people very helpful!)
