A question about the function canocorr

>> x = rand(3,5) >> y = rand(3,6) >> rank(x)

ans =

     3
>> canoncorr(x,y)
Warning: X is not full rank. 
> In canoncorr at 88
Warning: Y is not full rank. 
> In canoncorr at 97

ans =

         0         0
         0         0
    1.5835    1.7374
         0         0
    2.0226   -0.9926

Actually both the rank of x and y are 3,but why the matlab reports that X and Y are not full rank?
