求救builder for java

apiter

M文件

1. % snDistribution.m 标准正态分布
   
2. function y=snDistribution()
   
3. fun='exp(-(x^2)/2)';
   
4. y=int(fun,-inf,0);
   
5. end

复制代码

在matlab中测试可以通过，为什么通过builder for java生产jar文件调用的时候，


import Matlab.SNDistribution;
import com.mathworks.toolbox.javabuilder.*;
public class TestMain {        
public static void main(String[] args) throws MWException{            
           Object []result=null;            
           SNDistribution snd =new SNDistribution();
           result=snd.snDistribution(1);
           System.out.println(result[0]);
           snd.dispose();
           snd=null;        
       }
}

出现如下错误：
??? Undefined function or method 'int' for input arguments of type 'char'.
