Determine whether code is running in deployed or MATLAB mode
x = isdeployed returns logical 1 (
when the function is running in deployed mode using MATLAB® Runtime and 0 (
false) if it is running in a MATLAB session.
An application running in deployed mode consists of a collection of MATLAB functions and data packaged using MATLAB Compiler™ into software components that run outside of a MATLAB session using MATLAB Runtime libraries.
Access Files from Deployed Functions
You can access files included in a packaged application by
which function, or by specifying the file location
Add a file such as
extern_app.exe to your MATLAB
Check if the code is running in deployed mode by using
isdeployed. Then, obtain the path to the file by
if isdeployed locate_externapp = which(fullfile('extern_app.exe')); end
whichfunction returns the path to the file
extern_app.exe, as long as it is located within the deployable archive.
For more information, see Access Files in Packaged Applications.
Protect Use of
The path of a deployed application is fixed at compile time
and cannot change. Use
isdeployed to ensure that the
application uses path modifying functions, such as
if ~(ismcc || isdeployed) addpath(mypath); end
You cannot use the
doc function to open
the Help browser from a deployed application. Instead, redirect a help query to
the MathWorks® website.
if ~isdeployed doc(mfile); else web('https://www.mathworks.com/support.html'); end
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.
Usage notes and limitations:
Returns true and false as appropriate for MEX targets.
Returns false for SIM targets, which you should query using
Returns false for other targets.
