9 \class SOPHYA::DataTable
10 \ingroup HiStats
11 This class can be used to organize data in table (row-column) form.
12 Each column holds homogeneous data (same data type), while different
13 columns can be used for different data types
14 (integer, float, string ...).
15 The whole data set is kept in memory.

21 \code
22 #include "datatable.h"
23 // ...
24 DataTable dt(64);
25 dt.AddFloatColumn("X0_f");
26 dt.AddFloatColumn("X1_f");
27 dt.AddDoubleColumn("X0X0pX1X1_d");
28 double x[5];
29 for(int i=0; i<63; i++) {
30 x[0] = (i%9)-4.; x[1] = (i/9)-3.; x[2] = x[0]*x[0]+x[1]*x[1];
31 dt.AddRow(x);
32 }
33 // Printing table info
34 cout << dt ;
35 // Saving object into a PPF file
36 POutPersist po("dtable.ppf");
37 po << dt ;
38 \endcode
39
40 DataTableRow objects can also be used to fill the table, or access the data, as
41 shown in the example below:
42 \code
43 // We use the same table as in the example above:
44 DataTableRow row = dt.EmptyRow();
45 row[0] = 83.3; row[1] = 20.; row[2] = 83.3*83.3+20.*20.;
46 dt.AddRow(row);
47 row["X0_f"] = 7.5; row["X1_f"] = 6.; row["X0X0pX1X1_d"] = 7.5*7.5+6.*6.;
48 dt.AddRow(row);
49 \endcode
