Mr. Tamura,

I suspect that the problem comes from the way you've defined the
matrices. For example, this defines two 3x1 matrices and displays them
as column vectors in MatrixForm:

    a={{1},{2},{3}}; b={{2},{3},{4}};
    a//MatrixForm
    b//MatrixForm

Or you could use

    a={{1,2,3}}//Transpose; b={{2,3,4}}//Transpose;

Now, enter

    c=a.Transpose[b]
    c//MatrixForm

to get the 3x3 product.
