限时删除!!

我需要用FORTRAN输出一个矩阵.我有一个可以计算值的有效代码,但我得到的不是矩阵,而是一列.矩阵很大,ixj =〜2000x2000.

I need to output a matrix with FORTRAN. I have a working code that calculates the values, but instead of a matrix, I get single a column. The matrix is huge, ixj = ~2000x2000.

这是我的示例代码:

  open(19, file="results1.txt", status="old", position="rewind",
 & action="write")

  do j=0,p
  do i=0,o
  write(19,*) mat_user_yield_surface(d, eps(i), deps(j), 200.0d0)
  end do
  end do

  close(19)

推荐答案

使用隐式do循环:

do j=0,p
   write(19,'(2000g22.14)') (mat_user_yield_surface(d, eps(i), deps(j),200.0d0),i=0,o)
end do

我建议不要使用"o"作为变量名,因为它很容易与零混淆.

I suggest not using "o" as a variable name, since it is easily confused with zero.
