修改自wiley的书中的各种遗传算法（GA）matlab代码，还包括其他一些算法如粒子群优化，蚁群优化等，均已修改好用！(Modified since the book wiley various genetic algorithms (GA) matlab code, also includes a number of other algorithms such as PSO, ant colony optimization and so on, have been modified handy!)

使用LMS算法进行盲多用户检测，并计算出信干比和误码率(LMS algorithm using the blind multi-user detection, and calculate the signal to interference ratio and bit error rate)

利用非数NaN对所选图像进行镂空、透视、剪切处理。(few NaN using non-selected images of Pierced, perspective, shear processing.)
