hello everybody!

I want to create a random symmetric matrix which have det=2. I just made it like this, no better than those ones. Thanks!

Doixung := proc (n)

local A, i, j; A := Matrix(n);

n := LinearAlgebra[Dimension](A);

for i to n do A[i, i] := RandomTools[Generate](integer(range = 1 .. 20))

   end do;

for i to n do

     for j to n do

           while j < i do A[i, j] := RandomTools[Generate](integer(range = 1 .. 20)) end do;

           while i < j do A[i, j] := A[j, i] end do

     end do

end do;

print(A) end proc
