我正在编写用于 LU 分解的代码,但我不知道如何修复第 8 行指出的“意外数据声明语句”(我在这里声明一个数组。请参阅代码片段)。为什么会出乎意料?

PROGRAM LUdecomp
IMPLICIT INTEGER (I-K,N), REAL (A-H, L-M,O-Z)
INTEGER, PARAMETER :: N=3
REAL, DIMENSION (N,N) :: A,L,U
A = reshape((/3.,1.,4.,4.,2.,0.,3.,2.,3./),(/3,3/)) !exemplo do Bortoli*******
REAL, DIMENSION(3) :: B=(/9.,3.,-2./),Z,X
OPEN(1,file = 'LUFACTOR.out')

! FORALL (I = 1:N, J = 1:N) A(I,J) = 1.0/REAL(I+J-1)
!-------Fazendo a fatoração A = LU-----------------------------
CALL LU(N, A, L, U)
DO I=1,N
WRITE(*,10)(L(I,J), J=1,N), (U(I,J), J=1,N)
END DO
