Hi
Thanks, really it was the problem ... I fix it with a *try ... catch*, once
that I want a formatted output ... so the code is such like:
...................................................
try
{
for (int i = 0; i < mat_size; i++) {
os << "\n" << i << "|" ;
for (int j = 0; j < mat_size; j++) {
os.width(1);
//os << matrix(i,j) << " ";
if ( matrix(i,j).val() == 1 )
os << j << " ";
else
os << "_" << " ";
}
}
}
catch(std::exception &e)
{
std::cerr << "\n" << e.what()
<< "\t PRINT OUTPUT: NON DEFINITION for MATRIX YET" << std::endl;
}
.............................................................................................................................
So, now in blue and red nodes .... the gist's message is:
BoolVar::val: Attempt to access value of unassigned variable PRINT
OUTPUT: NON DEFINITION for MATRIX YET
Is there any alternative or better for this solution? Is there any function
to check if all the values of a variable are already instancied/assigned? In
this case, the variable is a matrix.
Thanks
