## SPRINTF Formated String Output Function (C-Style)

Section: Input/Ouput Functions

### Usage

Prints values to a string. The general syntax for its use is

      y = sprintf(format,a1,a2,...).

Here `format` is the format string, which is a string that controls the format of the output. The values of the variables `a_i` 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 `sprintf` command is not vectorized! Each variable must be a scalar. The returned value `y` contains the string that would normally have been printed. For more details on the format string, see `printf`.

### Examples

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.

    --> 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']
