问题描述
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.
