<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>Prints values to a string. The general syntax for its use is </p>
<pre class="fragment"> y = sprintf(format,a1,a2,...).
</pre><p> Here <code>format</code> is the format string, which is a string that controls the format of the output. The values of the variables <code>a_i</code> are substituted into the output as required. It is an error if there are not enough variables to satisfy the format string. Note that this <code>sprintf</code> command is not vectorized! Each variable must be a scalar. The returned value <code>y</code> contains the string that would normally have been printed. For more details on the format string, see <code>printf</code>. </p>
<h1><a class="anchor" id="Examples"></a>
Examples</h1>
<p>Here is an example of a loop that generates a sequence of files based on a template name, and stores them in a cell array.</p>
<pre class="fragment">--> l = {}; for i = 1:5; s = sprintf('file_%d.dat',i); l(i) = {s}; end;
--> l
ans =
[file_1.dat] [file_2.dat] [file_3.dat] [file_4.dat] [file_5.dat]
