粒子群参数优化算法子程序，可以实现多个组合参数的优化，采用实数编码。(particle swarm optimization )

用来计算地球表面两点之间的距离，该程序通过输入两点的经纬度坐标确定两点的距离，可用于各种工程应用当中(The Earth s surface used to calculate the distance between two points, two points in the program by entering the latitude and longitude coordinates to determine the distance between two points can be used in a variety of engineering applications which)

说明：  用matlab仿真的递推极大似然法辨识程序，可用来进行系统辨识，很好用(simulation using Matlab Recursive maximum likelihood method identification procedures, which can be used for system identification, good use)

等温线，matlab等温线经典程序，内置数据-IIsotherms ， (The isotherm, matlab isotherm classic program, built-in data-IIsotherms,)

"试验设计"是很多工程人员尤其是化学工作者经常要面对的话题，“试验设计”可以为我们的工作和科研节省大量的人力，物力和财力！本人结合自己在试验过程中的经历总结了所有设计过程中可能遇到的设计方案，并且把它们写成matlab源代码的形式，以此方便大家工作和学习上的使用。()

等间距线性阵列，阵元数M=8，阵元间距d= λ /2，等幅加权，目标方位φr =0°。产生空间白噪声矢量（复高斯分布）。 设阵列信号矢量元素s(m)=exp[j mψr]，其信号幅度为1，该阵元接收机附加的高斯噪声为n(m)=nmr+jnmi，其中实虚部均为独立同分布N(0, σ2)的高斯随机数，则该通道合成信号x(m)=s(m) + n(m)，其中信噪比为： SNR = 10 lg[1/(2σ2)] = – 3 – 10 lg(σ2) (dB) (The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted target azimuth φR = 0. Space generated white noise vector (complex Gaussian distribution). Let array signal vector elements s (m) = exp [j mψr], the signal amplitude, the element receiver additional Gaussian noise n (m) = nmr+jnmi which the real and imaginary parts are independent and identically distributed N ( Gaussian random numbers of 0, σ2), the channel the synthesis signal x (m) = s (m) the PPLS n (m), where SNR is: SNR = 10 lg [1/(2σ2)] =- 3- 10 lg (σ2) (dB))

This is a matlab code of SEP protocol that simulates the life of the sensor network.
