VAR estimation in Matlab and STATA

I am running VAR(2) model with two variables, say A and V, with some restrictions on the estimating matrix. Following is the code that I am running in Matlab.

if true
restriction = [1,0;1,1];
Spec = vgxset('n',2,'ARsolve',{logical(restriction),logical(restriction)});
Y = [ A, V ];
[EstSpec,EstStdErrors,LLF,W] = vgxvarx(Spec,Y,[],[],'CovarType','full');
end

The results in Matlab and STATA by comparison are

Model  : 2-D VAR(2) with No Additive Constant
         Conditional mean is AR-stable and is MA-invertible
         Standard errors without DoF adjustment (maximum likelihood)
     Parameter   Matlab Value   Stata Value

I am using MATLAB Version 7.11.0.584 (R2010b) with Econometrics Toolbox Version 1.4 and Stata 11.1 for Windows. Can anybody help me why they are different.
