说明：  如何用winrats做garch-bekk模型(how to use winrats creat garch-bekk)

this ile has been written to my friends in pudn and i believe it is useful for u. tjhanks for ur attention

说明：  很好用 ， 实验过的， 素轻松判定素数数。(sushu)

波束形成就是从传感器阵列重构源信号。（1）、通过增加期望信源的贡献来实现；（2）、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复(From sensor array beamforming is reconstructing source signal.(1), by increasing the expected source contribution to achieve (2), by suppressing interference sources.Classic beamforming need observation direction (expected source direction).Blind beamforming is trying to not expect source direction information of source of recovery)
