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.

Número incorrecto de argumentos de salida

Si llama a una función de MATLAB sin argumentos de salida o con más de un argumento de salida, debe proporcionar ese número en llamadas al método feval del motor.

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.
