Nicola,
    Re. your first question:

In[963]:=
ClearAll[A];
A = {{x1, x2, x3, x4, x5}, {y1, y2, y3, y4, y5}};
Dimensions[A]
Transpose[A]
Dimensions[%]

Out[965]=
{2, 5}

Out[966]=
{{x1, y1}, {x2, y2}, {x3, y3}, {x4, y4}, {x5, y5}}

Out[967]=
{5, 2}

>One more questions, if you don't mind. How can I have the starting matrix A
