laser18

matlab语言写的计算八木天线的程序，可以改变单元的数量，给出各个阵子的电流分布和方向图 (matlab language computing Yagi antenna program, you can change the number of units each time around given the current distribution and orientation map)

说明：  该LINGO程序的功能是：求出工程项目的收益的净现值和每道工序的最优开工时间，约束条件是紧前紧后约束，以及资源约束。。。(The program' s function is LINGO: the project proceeds to derive the net present value of each procedure and the optimal start time constraints are tight after the former tight constraints, and resource constraints. . .)

APRIORI ALGORITHM IMPLEMENTATION
