<H2>SPRINTF Formated String Output Function (C-Style)
</H2>
<P>
Section: <A HREF=sec_io.html> Input/Ouput Functions </A>
<H3>Usage</H3>
Prints values to a string. The general syntax for its use is
<PRE>
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>.
<H3>Examples</H3>
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.
<PRE>
--> 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]
