MATLAB JA Builder在MCRConfiguration中抛出NullPointerException
||
我正在尝试使用JA Builder从Java执行MATLAB函数。
我遵循了MATLAB JA Builder帮助文档-HelloWorld和MagicSquare示例，每次都收到以下堆栈跟踪：

安装MCR时，安装程序会告诉您其所需的值（取决于您的mcrroot，即安装MCR的目录）。例如套装董碘奴星
export LD_LIBRARY_PATH=/usr/lib/matlab-8.6/runtime/glnxa64 \\ /usr/lib/matlab-8.6/bin/glnxa64 \\ /usr/lib/matlab-8.6/sys/os/glnxa64 \\ /usr/lib/matlab-8.6/sys/opengl/lib/glnxa64
