13.2.13. Macro “dataserverComputeCorrelationMatrixVector.C”

13.2.13.1. Objective

This part shows the complete code used to produce the console display in Special case of vector.

13.2.13.2. Macro Uranie

    TDataServer *tdsop =new TDataServer("foo","poet");
    tdsop->fileDataRead("tdstest.dat");

    // Consider a and x attributes (every element of the vector)
    TMatrixD globalOne = tdsop->computeCorrelationMatrix("x:a");
    globalOne.Print();

    // Consider a and x attributes (cherry-picking a single element of the vector)
    TMatrixD focusedOne = tdsop->computeCorrelationMatrix("x[1]:a");
    focusedOne.Print();
