Using the DataVector object

This example shows how to initialize a DataVector object, store it to a file and then to restore it back.

#include <sgpp/base/datatypes/DataVector.hpp>
 
#include <iostream>
 
 
using sgpp::base::DataVector;
 
int main() {

We create a DataVector and fill it with 3 values

  DataVector v;
  v.append(1.0);
  v.append(2.0);
  v.append(3.0);

We save the DataVector to file

  v.toFile("dataVectorTest.vec");

We load the saved DataVector and then save it again (for no particular reason)

  DataVector w = DataVector::fromFile("dataVectorTest.vec");
  w.toFile("dataVectorTest2.vec");
}
