Question

我正在使用MatLab2013a 64位和Java7。我正在尝试做的是通过javabuilder从Java调用matlab函数，我创建了一个matlab项目来编译函数，以下是我的matlab函数

function SP=imagerotate(filename,theta)
    I=imread(filename);
    SP=imrotate(I,theta);

然后我将它添加到名为RotateImage的类中（这是编译Matlab函数的常用过程）。并且没有发生错误。然后我创建了一个Java项目并添加了distrib\flying.jar和C:\Program Files\MATLAB\MATLAB Compiler Runtime\v81\toolbox\javabuilder\jar\javabuilder.jar。当我尝试测试它时，发生了一个错误。

import flying.RotateImage;

public class Main {

        try {
            System.out.println("Begin");
            RotateImage flyingDraw = new RotateImage();
            System.out.println("Middle");
            MWNumericArray theta = new MWNumericArray(90, MWClassID.INT16);
            String filename=new String("C:\\Users\\ssj-at-work\\Desktop\\Picture\\GN20130625_1.jpg");
            Object img[]=null;
            img=flyingDraw.imagerotate(1,filename,theta);
            int[] k=((MWNumericArray) img[0]).getDimensions();
            for (int i:k){
                System.out.println(i);
            }
            System.out.println("Here");
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

错误信息如下
