Java调用matlab接口代码：

System.out.println( System.getProperty("java.library.path"));
try {

} catch (MWException e) {
throw new RuntimeException(e);

}

请问如何解决？
根据日志，似乎是在加载MATLAB的动态库时出现了问题。具体来说，这个问题可能是由于动态链接器（ld）无法找到MATLAB库而导致的。这可能是由于以下原因之一引起的：
1.MATLAB库的路径没有被正确设置 - 确保在您的环境变量中设置了MATLAB库路径。您可以在系统环境变量中设置LD_LIBRARY_PATH，以指定MATLAB库所在的路径。另外，还需要确保MATLAB库的路径在系统的动态库搜索路径中。
2.缺少MATLAB库 - 您的系统可能没有安装MATLAB或MATLAB Runtime。如果是这样，您需要先安装它们才能正确地加载MATLAB库。
3.不兼容的MATLAB版本 - 如果您使用的MATLAB版本与您的代码中使用的版本不兼容，则可能会发生此错误。请确保您的代码和MATLAB版本兼容。
