You could define a function like the following:
mGreater[a_, b_] := MatrixQ[MapThread[Greater, {a, b}, 2], TrueQ]
a = {{2, 3}, {4, 5}}; b = {{1, 2}, {2, 3}};
In[32]:= mGreater[a, b]
Out[32]= True
In[33]:= mGreater[b, a]
Out[33]= False

I am using mathematica for practical purpose.
I wonder how can I perform Matrix comparison.
For instance:
a={{2,3},{4,5}}; b={{1,2},{2,3}};
a>b
I want the result is True.
But it seems that Mathematica can not recognize it.
I do not know how I can solve it? Are there any additional package to be added?
Can any one with kindness help me?
