Question: Multiplication with transpose matrix

 

a := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = 3, (2, 2) = 4})with(LinearAlgebra)

 

a.a^T = (Matrix(2, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = 3, (2, 2) = 4})).(Matrix(2, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = 3, (2, 2) = 4}))^TNULL

I am not getting the answer.

I want to get the answer for this product of matrix and its tranport.

I do not want to create transport matrix again for this calculation.

The transporse matrix b is

b := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 3, (2, 1) = 2, (2, 2) = 4}) = Matrix([[1, 3], [2, 4]])

a.a^T is equal to a.b = Matrix([[5, 11], [11, 25]])NULL

For large matrices i cannot do this. Hence this request.Any one please send the code. Thanks.
