我尝试使用nxn矩阵格式编写输出 file.dat 。
我编写了代码,但输出是一列值 f。
现在的问题是:如何更改要写入的文件的输出格式?
从: 1 2 4 5 ...
到:1,2,3,4 // 5,6,8,.. //
program eccen
implicit none
integer, parameter:: grid=800
integer::i,j,k,n,m
real*8,allocatable::f(:,:)
real*8::xx(grid),yy(grid),mval,Mxval
real*8,allocatable::x(:),y(:)
open(10,file='3d_disk.txt')
n=0
DO
READ(10,*,END=100)
n=n+1
END DO
100 continue
rewind(10)
allocate(x(n),y(n))
do i=1, n
read(10,*) x(i),y(i)
end do
mval=-20.
Mxval=20.
do i=1, grid
xx(i) = mval + ((Mxval - mval)*(i-1))/(grid-1)
yy(i) = mval + ((Mxval - mval)*(i-1))/(grid-1)
end do
open(20,file='3d_map.dat')
allocate(f(n,n))
f=0
do i=1,grid
do j=1,grid
m=0.
do k=1, n
if (x(k) > xx(i) .and. x(k) < xx(i+1) .and. &
& y(k) > yy(j) .and. y(k) < yy(j+1)) then
m=m+1 ! CONTA IL NUMERO DI PARTICELLE
end if
end do
f(i,j)=float(m+1)
我认为修改必须来自这里:
write(20,*) f(i,j)
end do
write(20,*)
print *,i
end do
end program eccen
至:
do i=1,grid
do j=1,grid
write(20,*) f(i,j)
end do
end do
end do
write(20,*)
print *,i
end do
end program eccen
