Using feval

In standalone C and C++ modes, the pragma

%#function <function_n ame- list>

informs MATLAB Compiler that the specified function(s) should be included in

the compilation, whether or not the MATLAB Compiler dependency analysis

detects it. Without this pragma, the M ATLAB Co mpiler dependency analys is

willnotbeabletolocateandcompileallM-filesusedinyourapplication.

This pragma adds the top-level function as well as all the subfunctions in

thefiletothecompilation.

You cannot use th e

%#function pragma to refer to functions that are not

available in M-code.

Example: Using %#function

A good coding technique involves using % #fu nction in your code wherever

you use

feval statements. This example shows how to use this technique

to help MATLAB Compiler find th e appropria t e files during com pile tim e,

eliminating the need to include all the files on the command line.

function ret = mywindow(data,filterName)

%MYWINDOW Applies the window specified on the data.

% Get the length of th e data.

N= length(data);

% List all the possible windows.

% Note the list of fun ctions in the following function pragma is

% on a single line of code.
