我正在使用https://code.google.com/p/matlabcontrol/wiki/Walkthrough中的以下程序。我希望使用Matlab控件在Java中调用Matlab函数。我在程序中导入了matlabcontrol。
前两个示例程序对我来说效果很好。
public static void main(String[] args) throws MatlabConnectionException, MatlabInvocationException
{
//Create a proxy, which we will use to control MATLAB
MatlabProxyFactory factory = new MatlabProxyFactory();
MatlabProxy proxy = factory.getProxy();
//Create a 4x3x2 array filled with random values
proxy.eval("array = randn(4,3,2)");
//Print a value of the array into the MATLAB Command Window
proxy.eval("disp(['entry: ' num2str(array(3, 2, 1))])");
//Get the array from MATLAB
MatlabTypeConverter processor = new MatlabTypeConverter(proxy);
MatlabNumericArray array = processor.getNumericArray("array");
//Print out the same entry, using Java's 0-based indexing
System.out.println("entry: " + array.getRealValue(2, 1, 0));
//Convert to a Java array and print the same value again
double[][][] javaArray = array.getRealArray3D();
System.out.println("entry: " + javaArray[2][1][0]);
//Disconnect the proxy from MATLAB
proxy.disconnect();
}
当我在Windows上运行该程序时,Java给我以下错误:
C:\Program Files\Java\jdk1.6.0_45\bin>javac Helloworld3.java
Helloworld3.java:61: cannot find symbol
symbol : class MatlabTypeConverter
location: class Helloworld3
MatlabTypeConverter processor = new MatlabTypeConverter(proxy);
^

MatlabNumericArray array = processor.getNumericArray("array");

任何帮助,将不胜感激!
谢谢。
最佳答案
顺便说一句,我得到了答案。我们需要将文件导入为:
import matlabcontrol.extensions.MatlabTypeConverter;
现在,它工作正常!
