Question

我在MATLAB中设计了一个并行程序，我需要将它部署到一个JAVA库中，以便我可以在eclipse中使用这个程序。使用已部署的库时，出现问题，这是错误信息：

Error using initclient (line 37)
Java exception occurred: 
java.lang.NullPointerException
    at java.util.logging.Logger.demandLogger(Logger.java:339)
    at java.util.logging.Logger.getLogger(Logger.java:390)

Error in distcomp/schema (line 11)



Error in parallel_function (line 430)



Error in readingsaad (line 18)



Error in mainfunction (line 14)

这是为什么？请帮助我......提前谢谢。

Ps我确定在使用MATLAB时遇到问题 - “parfor”，我已经部署了另一个没有这个问题的程序。

如何在MATLAB中部署并行程序，将在JAVA中使用？
