NIEDERREITER2_DATASET <br> Create a Niederreiter Dataset, Base = 2.
</h1>
<hr>
<p>
<b>NIEDERREITER2_DATASET</b>
is a FORTRAN90 program
which creates a Niederreiter quasirandom dataset with base 2.
</p>
<p>
<blockquote>
<b>niederreiter2_dataset</b> <i>m</i> <i>n</i> <i>skip</i>
</blockquote>
where
<ul>
<li>
<i>m</i> is the spatial dimension;
</li>
<li>
<i>n</i> is the number of points to generate;
</li>
<li>
<i>skip</i> is the number of initial values to skip.
A recommended value is 4096.
</li>
</ul>
The data is written to the file <b>niederreiter2_<i>m</i>_<i>n</i>.txt</b>.
