<H3><FONT COLOR="#CC3333">Note</FONT></H3>
For a vector of dimension n, <A HREF="../Vec/VecSet.html#VecSet">VecSet</A>() computes
<pre>
x[i] = alpha, for i=1,...,n,
</pre>
so that all vector entries then equal the identical
scalar value, alpha. Use the more general routine
<A HREF="../Vec/VecSetValues.html#VecSetValues">VecSetValues</A>() to set different vector entries.
