通过遗传算法计算多背包问题 (Computing multi knapsack problem by genetic algorithm)

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)

MATLAB的用户图像界面（GUI）（源码可见），可直接运行，依次为打开原图-三分图开输出alpha图，接着打开背景图可合成新图像(MATLAB user graphical interface (GUI) (source visible), can be directly run, followed by open the original- plans to open three-point output alpha map, and then open a new background image can be synthesized)

This program solves the following equation using Newton-Raphson method.
