Assignment has more non-singleton rhs dimensions than non-singleton subscripts

Hi i have problem with this error,please help me for this

    A=zeros(4,8,9,8,2);
for l=1:4
    for m=1:8
        K=1:.25:3;
        for kindex=1:9
            for j=1:8
            for n=[0, 1]
A(l, m, kindex, j, n+1)=[a11vec(l, m, kindex, j, n+1),a12vec(l, m, kindex, j, n+1),a13vec(l, m, kindex, j);a21vec(l, m, kindex, j, n+1),a22vec(l, m, kindex, j, n+1),a23vec(l, m, kindex, n+1);a31vec(l, m, kindex, j),a32vec(l, m, kindex, n+1),a33vec(l, m, kindex, j, n+1)];
            end
            end
        end
    end
end
end

A is the martrix(3*3) and i have a11,a12,a13,a21,a22,a23,a31,a32,a33 for l,m,k, and n Variables. but when run,matlab said: "Assignment has more non-singleton rhs dimensions than non-singleton subscripts"

[per isakson]

The RHS is a scalar

K>> A( l, m, kindex, j, n+1 )
ans =
     0
K>>

the LHS is a 3x3 matrix

K>> whos z
  Name      Size            Bytes  Class     Attributes
  z         3x3                72  double

where

a11vec = ones( 4, 8, 9, 8, 2 );
...
for n=[0, 1]
    z = [ a11vec(l,m,kindex,j,n+1), a11vec(l,m,kindex,j,n+1), a11vec(l,m,kindex,j)
          a11vec(l,m,kindex,j,n+1), a11vec(l,m,kindex,j,n+1), a11vec(l,m,kindex,n+1)
          a11vec(l,m,kindex,j)    , a11vec(l,m,kindex,n+1)  , a11vec(l,m,kindex,j,n+1)
        ];
    %
    A( l, m, kindex, j, n+1 ) = z;
end
