Appeler MATLAB à partir de Java
Appelez des fonctions MATLAB et évaluez des instructions MATLAB depuis des programmes Java de manière synchrone ou asynchrone. Les programmes Java peuvent transmettre des données à l’espace de travail MATLAB et obtenir des données de celui-ci. Le moteur supporte les applications Java créées avec JDK™. Pour plus d’informations sur les versions, consultez Versions of OpenJDK Compatible with MATLAB by Release (Versions de OpenJDK compatibles avec MATLAB par version).

Présentation de l’API Engine Java
- Java Engine API Summary
Here is a summary of the classes and methods available to use the MATLAB Engine API for Java. - Java Data Type Conversions
The MATLAB engine API provides mappings to pass Java data types to MATLAB and pass MATLAB data types to Java, including Java classes to accommodate MATLAB handle objects, cellstrs, structures, and complex arrays.
Utiliser MATLAB Engine API pour Java
- Start and Close MATLAB Session from Java
Start the Java engine session synchronously or asynchronously and you can pass startup options to MATLAB. - Connect Java to Running MATLAB Session
Connect the Java engine to a running MATLAB session that has been started as or converted to a shared session. - Execute MATLAB Functions from Java
Pass Java variables to MATLAB function calls and return values to Java. - Evaluate MATLAB Statements from Java
Evaluate MATLAB expressions from Java and write variables into the MATLAB base workspace. - Pass Variables from Java to MATLAB
Pass variables from Java to MATLAB as function arguments or by placing those variables in the MATLAB base workspace. - Pass Variables from MATLAB to Java
Get variables from the MATLAB workspace and map them to the appropriate Java type. - Redirect MATLAB Command Window Output to Java
Redirect standard output from the MATLAB command window to Java.
Types MATLAB spécialisés pour Java
- Using Complex Variables in Java
Define complex numbers in Java using theComplexclass. - Using MATLAB Structures in Java

Résolution des problèmes
The MATLAB Engine API for Java defines specific exception classes for MATLAB.
Pass Java Array Arguments to MATLAB
MATLAB and Java display multidimensional arrays differently, but indexed references to array elements produce the same results.
Incorrect Number of Output Arguments
If you are calling a MATLAB function with no or more than one output argument, you must
provide that number in calls to the engine feval
method.
In certain cases, you must convert to specific MATLAB types to support the requirements of the MATLAB function you are calling.
