[厲害]張大神

張大神(不是張大嬸),昨天傳授給我一個寫matlab code高招,讓我的程式(1D, time-dependent),在N=20, t=0.5的狀態下快了十倍以上,真是太神奇了,原來for loop真的很糟糕。
If you love someone, let it be and set him free. If he comes back to you, it's meant to be.

which 張大神 is this~~ can I also learn some 招....? Orz
嗯迴圈真的超慢!
matlab 要快就是要把所有東西都弄成矩陣去運算~
就是Yang Zhang。
我改了快十倍竟然還算了八小時,那沒改前我都可以去撞牆了。
而且由於電腦被占住了,我都沒辦法寫blog(哈)。
