Hi,

I want to display the matrix M, I used return M, in this procedure, but no matrix M displayed.

restart;
N:=2:
N:=2;
ff:=proc(N)
local M,i,p;
M:=array(1..2*N+1,1..2*N+1):
for i from 1 to 2*N+1 do
for  p from 1  to 2*N+1  do
   if p=1 then M[p,i]:=-2;
    elif  p=2*N+1  then M[p,i]:=-3;
else
M[p,i]:=0;
end if; end do; end do;
return M;
end proc;
