3.6.3.3. Regular mode

In the example of Construction of a simple OAT design-of-experiments, if we change the “step 3” to:

TOATDesign oatSampler(tds, "regular", 4);

the OAT design becomes:

Each factor is modified 4 times, and its values are regularly spaced over the interval of variation (see Macro “samplingOATRegular.C” for complete code).
