本程序是是实现一种波束形成算法，从而得到波达方向，有一定的参考价值。。(This program is is to achieve a beam forming algorithm, resulting in DOA, a certain reference value. .)

用斐波那契额法求函数极小值，它是一种双向收缩的方法，它的收缩率是0.618(Fibonacci amount of law and the function minimum, it is a two-way contract, the contraction rate is 0.618)

计算机仿真大集合，包括课件，各种M文件集合，值得拥有！(Large collection of computer simulation, including the courseware, a variety of M-file collection worth having!)

系统的结构参数和负荷情况都已给定时，调节可利用的控制变量(如发电机输出功率、可调变压器抽头等)来找到能满足所有运行约束条件的，并使系统的某一性能指标(如发电成本或网络损耗)达到最优值下的潮流分布。(Optimal power flow(OPF) is a fundamental tool in power system planning and operation.)

matlab中几种常用的程序，对于熟悉matlab编程有很大帮助(some code in matlab，is useful for the new fish)

MFDFA的另一种编程程序，对多重分型谱进行直接估计(A DERECT ESTIMATION OF THE MULTIFRACTAL SPECTRUM)

如果阵元间距小于半波长，则阵元间会产生耦合。如果阵元间距大于半波长，则阵列上会现多余的旁瓣，从而降低天线阵列的性能。而当阵列间距选取为半波长时，所估测出的效果最优。(If the array element spacing is less than half wavelength, it will produce coupling between array elements. If the array element spacing is greater than half wavelength, the array will now be extra sidelobes, thus reducing the performance of the antenna array. When the array spacing is half wavelength selection, the best estimate the effect.)
