无法在Unix环境中的MATLAB运行时上运行Java代码

将matlab函数导出到java包后。我尝试在unix环境下运行以下代码，其中包含MATLAB运行时

import com.mathworks.toolbox.javabuilder.MWArray;
import com.mathworks.toolbox.javabuilder.MWCharArray;
import calibrationAPINew.Calibration;

public class CHIndexCalculation {
        public static void main(String[] args) {

              MWCharArray number1 = null;
              Object[] result = null;
              Calibration calibration = null;
              String data = "{\r\n" +
                        "\"tsId\" : \"121213\",\r\n" +
                        "\"datapoints\" : [0.1,0.2,0.3,0.4]\r\n" +
                        "}";

              try
              {
                 System.out.println("Input data: " + data);
                 number1 = new MWCharArray(data); // Array of Input to be sent to MATLAB Runtime
                 System.out.println("MWCharArray: " + number1);
                 calibration = new Calibration();
                 result = calibration.calibrationAPI(1,number1);

                 System.out.println("Output : " +  result[0]);
              }
              catch (Exception e)
              {
                System.out.println("Exception Occurred : " + e);
                 e.printStackTrace();
              }
              finally
              {
                 //MWArray.disposeArray(number1);
                 //MWArray.disposeArray(result);
                 //calibration.dispose();
              }

        }
}

我已经在unix上安装了matlabruntime box，并使用export语句设置了环境变量

export LD_LIBRARY_PATH=matlabrt/v92/runtime/glnxa64:matlabrt/v92/bin/glnxa64:matlabrt/v92/sys/os/glnxa64:matlabrt/v92/sys/opengl/lib/glnxa64

现在，当我尝试运行命令时（

calibrationAPINew.jar

是从MATLAB导出的jar文件）

我得到以下例外

com.mathworks.toolbox.javabuilder.MWException: Undefined function 'pdist2mex' for input arguments of type 'double'.

我知道这与MATLAB运行时有关，但我不知道是什么？同样的设置在windows环境下运行良好。

我认为matlab程序使用了一些已经为windows编译的mexfile，因此它在windows上运行得非常完美。由于MEX文件已经可用，它将在windows上完美工作。但是，当您的脚本无法找到linux对应的mexfile时，它会失败或尝试使用jar包中未包含的函数“pdist2mex”编译linux源文件。在windows中，不需要此函数，因此它可以正常工作。如果是这种情况，那么您可以从matlab将函数“pdist2mex”添加到jar中，或者您应该使用matlab手动将源代码编译为linux兼容的mex文件，然后尝试重新打包，然后matlab会自动将相应的mex文件包装到jar中

我将尝试一下
