<H3><FONT COLOR="#883300">Notes</FONT></H3>
All active columns (except the leading ones) are modified.
<P>
Other functions such as <A HREF="../BV/BVSetRandom.html#BVSetRandom">BVSetRandom</A>(), <A HREF="../BV/BVSetRandomColumn.html#BVSetRandomColumn">BVSetRandomColumn</A>(), and <A HREF="../BV/BVSetRandomCond.html#BVSetRandomCond">BVSetRandomCond</A>()
produce random numbers with a uniform distribution. This function returns values
that fit a normal distribution (Gaussian).
<P>
<H3><FONT COLOR="#883300">Developer Notes</FONT></H3>
The current implementation obtains each of the columns by applying the Box-Muller
transform on two random vectors with uniformly distributed entries.
