复化梯形函数，复化辛普森函数，龙贝格函数matlab算法(Complex trapezoidal function, complex function Simpson, dragon berg function matlab algorithm)

RSSI算法是指根据无线传感器接受到（目标物体）的信号指示强度，计算该信号在传播中的损耗，根据理论或者经验的信号传播模型将信号强度转换成距离。但是这种算法很容易受到天气，障碍物或人员流动的影响，导致测距不精确，从而定位精度不高。但是由于RSSI算法简单，成本低廉，很多无线通信模块提供RSSI值，所以RSSI算法依然应用在众多领域中。(RSSI algorithm is based on wireless sensor to receive the signal intensity (objects), calculate the signal in the transmission loss, according to the experience of the theory or the signal propagation model will be converted into a distance of signal strength.But this algorithm is very vulnerable to weather, obstacles or the influence of the flow of people, lead to range is not accurate, thus positioning accuracy is not high.But because the RSSI algorithm is simple, low cost, a lot of wireless communication module provides RSSI values, so the RSSI algorithm is used in many fields.)

说明：  多目标优化，遗传算法，适合于研究多目标优化的朋友 (Multi-objective optimization, genetic algorithm, suited to study multi-objective optimization of a friend)

共有4个MATLAB的实验内容和运用所学习的基本的知识去解决应这些问题。(Comprehensive experiment )

由一张图像提取圆形的边缘,得到离散的点来拟合椭圆,并简单的去除噪声,得到椭圆中心坐标.(Extracted by a picture rounded edges to fit the discrete points oval, and simply remove noise, get the coordinates of the center of the ellipse.)

本实验程序用于计算信号的包络和包络信号的频谱（包络谱）。 算法采用了Hilbert变换计算包络( This experiment is used to calculate the envelope (envelope) of the envelope and envelope of the signal. The algorithm uses a Hilbert transform to compute the envelope)

Example - 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the complex plane. So, it is interesting to visualize the plot around the unit circle. Calculating the unit circle.(Example- 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the complex plane.
