write result as matrix form

let us consider following matrix

a=[1 2 3;2 3 4;3 4 5;4 5 7]

a =

     1     2     3
     2     3     4
     3     4     5
     4     5     7

let us consider it's svd

[U E V]=svd(a)

U =

   -0.2738   -0.8708   -0.0062   -0.4082
   -0.3984   -0.2552   -0.3309    0.8165
   -0.5230    0.3605   -0.6557   -0.4082
   -0.7020    0.2159    0.6786    0.0000


E =

   13.5093         0         0
         0    0.6482         0
         0         0    0.2797
         0         0         0


V =

   -0.4032    0.8699    0.2841
   -0.5437    0.0220   -0.8390
   -0.7361   -0.4928    0.4641

if consider kronecker product of columns of U and V matrix

kron(U(:,1),V(:,1))

ans =

    0.1104
    0.1489
    0.2015
    0.1606
    0.2166
    0.2932
    0.2109
    0.2843
    0.3849
    0.2831
    0.3817
    0.5167

but it is returning as vector form,but i need matrix form,so how can i transform it to matrix insider kron product?maybe i should you reshape command,but could you help me to do it?thanks in advance

i have consider following change as Divakar adviced and it works fine

X=kron(U(:,1),V(:,1)')

X =

    0.1104    0.1489    0.2015
    0.1606    0.2166    0.2932
    0.2109    0.2843    0.3849
    0.2831    0.3817    0.5167
