(sampler_oat_toatdesign_regular_mode)=
# Regular mode

In the example of [](#sampler_oat_toatdesign_simple_oat), if we change the "step 3" to:

````{only} cpp
```cpp
TOATDesign oatSampler(tds, "regular", 4);
```
````

````{only} py
```python
oatSampler = Sampler.TOATDesign(tds, "regular", 4)
```
````

the OAT design becomes:

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/build/uranie/doc/sampler/use_cases/" + language + "/samplingOATRegular.log"
    + "\n"
    + ":language: none\n"
    + ":lines: " + console[language] + "\n"
    + "```"
}}

Each factor is modified 4 times, and its values are regularly spaced over the interval of variation 
(see [](#use_cases_macro_sampler_oat_regular) for complete code).
