3rd debugging example (2)

Next step: print out information 
  for (i = 0; i <= nx; i++) {
    for (j = 0; j <= ny; j++) {
      arglist = Py_BuildValue("(dd)", IND1(xcoor,i), IND1(ycoor,j));
      result = PyEval_CallObject(func1, arglist);
      IND2(a,i,j) = PyFloat_AS_DOUBLE(result);

#ifdef DEBUG
      printf("a[%d,%d]=func1(%g,%g)=%g\n",i,j,
	     IND1(xcoor,i),IND1(ycoor,j),IND2(a,i,j));
#endif
    }
  }
Run 
./make_module_1.sh gridloop3 -DDEBUG
