粒子群优化算法的寻优算法——非线性函数极值寻优

matlab基礎教程，適合剛接觸matlab的人(繁中)(matlab basic tutorial, suitable for those who use matlab (troditional chinese))

在secshortest中我希望只得到一条次短路,结果却出来好几条，因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。(I hope that in secshortest only a short time, the result is out of several, so when used to get at short circuit, can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest.)

自己编写的55行精短情诗代码，呈现红色背景、白窗心形图案及动态U型符号，释义“Need you !”，码农也能文艺！(55 lines fine short poems codes, showing heart-shaped background and dynamic symbol-U,meaning "Need you!")

波束域降阶Root-MUSIC算法,在子阵分解降阶的基础上,进一步将多项式的求根阶次降到与源数目相同,提出了求解降阶多项式的方法。该方法最大程度地减少了求根多项式的阶次和求解多项式的次数,并保持了Root-MUSIC算法的优良性能。显著降低运算量是其最大优点,仿真结果验证了降阶算法的有效性,并比较了不同阶次波束域Root-MUSIC算法的估计性能。 (Beamspace Reduced Order Root-MUSIC algorithm, based on the reduced-order sub-array decomposition further order of the polynomial rooting down with the same number of sources, proposed to solve the reduced-order polynomial method. This method minimizes the number of polynomial order and solving polynomial rooting and maintain the excellent performance of Root-MUSIC algorithm. Significantly reduce the amount of computation is its biggest advantage, simulation results show the effectiveness of the reduced-order algorithm, and compare the performance of different estimates of the order beamspace Root-MUSIC algorithm.)
