F77的循环语法不太理解~感谢~

哈哈哈

[Fortran] syntaxhighlighter_viewsource syntaxhighlighter_copycode

          do 150 k=n,2,-1
	       do 140 i=k,n
140            d(k-1,j)=d(k-1,j)-a(k-1,i)*d(i,j)
                 d(k-1,j)=d(k-1,j)/a(k-1,k-1)
150          continue

上面这段代码，如果改成F90的话，是不是这样的呢？

[Fortran] syntaxhighlighter_viewsource syntaxhighlighter_copycode

        do k=n,2,-1
            do i=k,n
                d(k-1,j)=d(k-1,j)-a(k-1,i)*d(i,j)
                d(k-1,j)=d(k-1,j)/a(k-1,k-1)
            end do
        end do

[mw_shl_code=fortran,true]do k=n,2,-1
    do i=k,n
        d(k-1,j)=d(k-1,j)-a(k-1,i)*d(i,j)

是不是没有continue的话，就只进行表明数字的那一行，如果有continue的话，就循环到continue

楚香饭

do   数字 .....
   ....A
   ....B
   ....C
数字   ....D

等效于

do  .....
   ....A
   ....B
   ....C
   ....D
End Do

不管有没有 continue
