USE dmd predict wrong result

Nobody has claimed this yet.

generator dmd
```
for(auto fileName:fileNames)
{

std::vector temp =utility.creatMedSingleSnapshot(ON_NODES,fileName,meshName,filedName,true);
values.push_back(temp);

int SizeData = temp.front().size();
double dt = 600.;//600 second
CAROM::DMD *dmd_u=new CAROM::DMD(SizeData,dt);

for(int i = 0;itakeSample(values[index][i].data(),i*dt);
}

dmd_u->train(16);
dmds.push_back(dmd_u);

double flux = p[index].front();
// double flux = 400.;
std::shared_ptr< CAROM::Vector> param_vector(new CAROM::Vector(1, false));
(*param_vector)(0) = flux;
param_vectors.push_back(param_vector);

index++;
}
```
predict code

```
CAROM::DMD *dmd_u_p;
CAROM::Vector desired_param(1, false);
desired_param(0) = 70.;//load flux
CAROM::getParametricDMD(dmd_u_p, param_vectors_ptr, dmds, &desired_param,
"IMQ", "LS", closest_rbf_val);

std::unique_ptr init(new CAROM::Vector(5548,true));//FEM point size is 5548
(*init)=20.;//init value
dmd_u_p->projectInitialCondition(init.get());
double predictTime = 18000.;
auto value2 =dmd_u_p->predict(predictTime);
```
one point value in snapshot as follow: step time 6000

when i predict 600s the value is 116 adn when i predict 18000s the value is -333. i don't konw why ?

Start with the CAROM::DMD calls to takeSample, train, projectInitialCondition, and predict, then inspect getParametricDMD with the IMQ and LS options. Reproduce the reported case using the supplied snapshot values and compare predictions at 600 and 18000 seconds; done means explaining or correcting the unexpected 116 and -333 results.
