Ffmatlib.idp import error

I am getting error in importing ffmatlib.idp .
Kindly comment me to figure it out.

Also, I am trying to save the solution for T over the entire domain [0,1]*[0,1].
by:

ofstream ff1("T_domain.dat");

for(int i = 0; i<=100; ++i)
{
for(int j = 0; j<=100; ++j)
{
  real xval = i/100.;
  real yval = j/100.;
  ff1<< xval<<","<<yval<<","<<T(xval, yval)<<endl;
}
}

But the output file contains the coordinate (o, yval).

Help me to get the solution for T over the entire domain and import of module ffmatlib.idp
