Llamar aMATLABdesdeJava

Escribir programas de Java^®que funcionen con MATLAB^®

Llame a funciones de MATLAB y evalúe instrucciones de MATLAB desde programas de Java de forma sincrónica o asincrónica. Los programas de Java pueden pasar datos hacia el área de trabajo base de MATLAB y obtener datos desde ella. El motor admite aplicaciones de Java creadas con JDK™.Para obtener más información sobre las versiones, consulteInterfaces de MATLAB a otros lenguajes.

Para llamar a las funciones de Java desde MATLAB, consulteBibliotecas de Java en MATLAB.

Solución de problemas

MATLAB Engine API Exceptions

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 enginefevalmethod.

Incorrect Java Data Types

In certain cases, you must convert to specific MATLAB types to support the requirements of the MATLAB function you are calling.
