f(i,0)=cdbl(g(0))
f(i,1)=cdbl(g(1))
f(i,2)=cdbl(g(2))
next
end sub
以上程序实现的是将符合条件的zuobiao.txt(此文件中是一些空间点的三维坐标,一个点一行)中的行赋值给s()数组,然后又需要将s()中的每一列作为一个数值向量进行赋值,上述程序仅仅是把s()中的数按列赋值给f()。
在实际的运行结果中出现了问题,还请大侠们帮忙!!

LoopLZ这代码的效率太差
就像你说的一样,确实是后面得到的结果是一样的。我很久以前学的vb,现在在解决问题的时候用上了,又重新学的,能达到目的就行了,根本没有效率可言。
谢谢你的指点,我的qq:51451112,希望以后可以多向你学习~
