loadlibrary function in MATLAB® allows you to load shared library into MATLAB.
Loading libraries using header files is not supported in compiled applications. Therefore,
to create an application that uses the
loadlibrary function with a header
file, follow these steps:
Create a prototype MATLAB file. Suppose that you call
loadlibrary with the
Run the following command in MATLAB only once to create the prototype file:
loadlibrary(library, header, 'mfilename', 'mylibrarymfile');
in the current folder. If you are on Windows®, another file named
library_thunk_pcwin64.dllis also created in the current folder.
Change the call to
loadlibrary in your MATLAB to the
Compile and deploy the application.
If you are integrating the library into a deployed application,
specify the library’s
.dll along with
library_thunk_pcwin64.dll, if created, using the
-a option of
mcc command. If
you are using Application Compiler or Library Compiler apps, add the
.dll files to the Files required for
your application to run section of the app.
If you are providing the library as an external file that is not
integrated with the deployed application, place the library
.dll file in the same folder as the compiled
application. If you are on Windows, you must integrate
library_thunk_pcwin64.dll into your compiled
The benefit of this approach is that you can replace the library with
an updated version without recompiling the deployed application.
Replacing the library with a different version works only if the
function signatures of the function in the library are not altered. This
library_thunk_pcwin64.dll are tied to the
function signatures of the functions in the library.
You cannot use
loadlibrary inside MATLAB to load a shared library built with MATLAB. For more information on
loadlibrary, see Limitations to Shared Library Support.
Operating systems have a
loadlibrary function, which loads
