The MATLAB Compiler incorporates startup.m into every generated executable and shared Used by MATLAB to establish the initial MATLAB search path, pathdef.m may be modified, Problematic path settings sometimes occur in these May have forgotten that the application relies on these path settings.

Path management commands often appear in startup or initialization code when it comes time to deploy your application, you Remove a directory from MATLAB's search path. Remove a directory from MATLAB's Java search path. addpath:Īdd a directory to MATLAB's Java search path. To change the way the application works, either by changing the functions it calls or the data files it loads.

Most of these functions should be avoided in deployed applications because they have the potential M-files to the path when my applications run in MATLAB: if ~isdeployedĪddpath /home/pwebb/mfiles/beta end MATLAB Commands that Directly Access the PathĪll M-file and Java functions rely on the state of MATLAB's internal paths, but only a few MATLAB commands directly access For example, this M-code adds my "beta"-quality Isdeployed function to skip over calls to path management functions in deployed applications. In cases where it is convenient to keep path management commands in your M-files when they run in MATLAB, you can use the In which it was developed: for example, when installed at a customer site. These guidelines become more important when the compiled application executes in an envrionment that differs from the one

Avoids accessing or changing the current directory.

Uses relative paths (or anchors paths to a known root via the matlabroot or ctfroot functions).

Does not change any path during execution.

When writing an application intended for deployment via the MATLAB Compiler, keep in mind that MATLAB applications typically interact with paths in at least three independent ways: The same path to look for executables and shared libraries, but most Unix systems search separate paths for these two types Which the operating system will look for executables and shared libraries, respectively. The two external paths list the locations Path, which specifies the directories in which MATLAB searches for Java functions. Though the MATLAB path is the most visible, of nearly equal importance is the MATLAB Java class Most familar, perhaps, is the MATLAB path, which affects how MATLAB determines which MATLAB function files to run and which MAT-files to open. MATLAB primarily interacts with four paths, two internal and two external: the MATLAB path the MATLAB Java class path the system path and the system load library path. MATLAB uses paths for two reasons: to determine which functions to execute Īnd to locate data files in the file system. MATLAB typically searches a path in list order, stoppingĪt the first file that matches the search criteria. Perhaps the most important of these is the mechanism by which MATLAB locatesįunctions and data files: MATLAB's search paths.Ī path consists of a list of directories that MATLAB searches to find files.

As a result, certain aspects of the execution environment that are malleable in MATLABīecome fixed or constant in a deployed application. One of the goals of the compilation process is to turn a flexible and easily modifiable MATLAB progam into a robust softwareĬomponent with consistiently predictable behavior: a compiled application should not be able to change which functions itĬalls or the way those functions work.

Relying on the Structure of External Paths.

MATLAB Commands that Directly Access the Path.
