[問題] function如何回傳陣列(矩陣)
想使用function回傳一整個陣列而不是一個數值，不知到與法該怎麼用
program main
real*8, allocatable :: a(:,:),a1(:,:))
integer*4 :: b=3
allocate (a(b,b),a1(b,b))
!allocate (a1(b,b))
allocate (a2(b,b))
a=0.d0; a1=0.d0;
a1(1,1:3)=1.5d0;
a(2,1:3)=2d0*a1(1,1:3)+5d0
write(*,*) a;
write(*,*) a1;
print * , '\'
write(*,*) add(b,a,a1)
pause
stop
end program main
function add(b,a,a1)
integer*4 :: b
real*8,allocatable :: a(:,:),a1(:,:)
allocate( a(b,b),a1(b,b) )
real*8, dimension(b,b) :: add
add=a+a1
return
end function add
跑出兩個錯誤訊息，不知道與法該怎麼用QQ
Error: A specification statement cannot appear in the executable section.
real*8, dimension(b,b) :: add
--------^
Error: The shapes of the array expressions do not conform.
add=a+a1
--------^
除此之外，順便問一下可以自動加入行號嗎....難道真的要一行一行打QQ?
我用的是Compaq Visual Fortran
謝謝
