Re: Out of Memory Problem (beginner)

To illustrate with a smaller matrix:

a = Table[i, {i, 1, 6}, {j, 1, 7}];
MatrixForm[one = Table[7i j, {i, 1, 6}, {j, 1, 6}]]
MatrixForm[two = a.Transpose[a]]
one == two

Out of Memory Problem (beginner)

I have a matrix of 6000 x 7000.
A = Table[i,{i,1,6000},{j,1,7000}]
I'd like to calculate A.Transpose[A].
But it appears "Out of Memory" problem after
trying to calculate for a long time.

Does anybody know how i can olve the above problem?

Thank you in advance,
