我试图从Mathematica中获取一张图片.

我尝试评估一些使用包中的方法生成图形的Mathematica代码.

如果我将代码粘贴到Mathematica Notebook,则会正确生成图形.

所以我的问题：

如何将这些图形转换为Java ???

这是我的示例代码：

ml = MathLinkFactory.createKernelLink("-linkmode launch -linkname 'F:\\APPS\\Wolfram

Research\\Mathematica\\7.0\\mathkernel.exe'");

ml.addPacketListener(new MyPacketListener());

ml.discardAnswer();

PacketListener stdoutPrinter = new PacketPrinter(System.out);

ml.addPacketListener(stdoutPrinter);

// In stringList there is all the INPUT for Mathematica

for (int i = 0; stringList.size() > i; i++)

{

System.out.println("Input" + "[" + i + "]" + stringList.get(i));

ml.evaluate(stringList.get(i));

ml.discardAnswer();

}

ml.close();

class MyPacketListener implements PacketListener {

public boolean packetArrived(PacketArrivedEvent evt)

throws MathLinkException {

if (evt.getPktType() == MathLink.TEXTPKT) {

KernelLink ml = (KernelLink) evt.getSource();

System.out.println(ml.getString());

}

return true;

}

输出是：

<

<

dataSet = CIP`ExperimentalData`GetQSPRDataSet02[];

CIP`Graphics`ShowDataSetInfo[{"IoPairs", "InputComponents", "OutputComponents"},

dataSet];

Number of IO pairs = 2169

Number of input components = 130

Number of output components = 1

mlrInfo = CIP`MLR`FitMlr[dataSet];

mlrInfoInInputForm = InputForm[mlrInfo];

pointSize = 0.025;

CIP`MLR`ShowMlrSingleRegression[{"ModelVsDataPlot", "CorrelationCoefficient"},

dataSet, mlrInfo, GraphicsOptionPointSize -> pointSize];

(*-Graphics-*)

(*

Out 1 : Correlation coefficient = 0.999373

*)

pointSize = 0.01;

CIP`MLR`ShowMlrSingleRegression[{"AbsoluteSortedResidualsPlot",

"AbsoluteResidualsStatistics", "RMSE"},

dataSet, mlrInfo, GraphicsOptionPointSize -> pointSize];

(*-Graphics-

Definition of 'Residual (absolute)': Data - Model

-1

Out 1 : Residual (absolute): Mean/Median/Maximum Value = 1.4 / 9.84 × 10 /

1

> 1.79 × 10

Root mean squared error (RMSE) = 2.063

*)

我如何获得这些-Graphics-？

谢谢您的帮助！
