问题描述
最近小弟想用java调用matlab，环境配置成功了，但是当我想调用matlab通过javabuild形成的java类是却出现了问题。首先我在matlab里写了.m函数文件，该函数需要输入4个参数，都是浮点型，之后形成java包之后，在形成的java文件中却只看到含有两个传递参数的java类。然后再在命令行执行java程序时，提示错误：...undefined'dis_fd_depth'forinputargumentsoftypt'double'希望得到各位前辈的指点！！！谢谢！！下面是matlab形成的java类：/**MATLABCompiler:4.8(R2008a)*Date:SunJul2615:17:182009*Arguments:"-B""macro_default""-W""java:dis_fd_depth,dis_fd_depthclass"*"-d""C:\DocumentsandSettings\Administrator\My*Documents\MATLAB\dis_fd_depth\src""-T""link:lib""-v"*"class{dis_fd_depthclass:C:\Documentsand*Settings\Administrator\桌面\dis_fd_depth.m}"*/packagedis_fd_depth;importcom.mathworks.toolbox.javabuilder.*;importcom.mathworks.toolbox.javabuilder.internal.*;importjava.util.*;/***The<code>dis_fd_depthclass</codeclassprovidesaJavainterfacetothe*M-functionsfromthefiles:*<pre>*C:DocumentsandSettingsAdministrator桌面dis_fd_depth.m*</pre>*The{@link#dispose}method<b>must</b>becalledona*<code>dis_fd_depthclass</code>instancewhenitisnolongerneededto*ensurethatnativeresourcesallocatedbythisclassareproperlyfreed.*@version0.0*/publicclassdis_fd_depthclassextendsMWComponentInstance<dis_fd_depthclass>{/***Tracksallinstancesofthisclasstoensuretheirdisposemethodis*calledonshutdown.*/privatestaticSet<Disposable>sInstances=newHashSet<Disposable>();/***Maintainsinformationusedincallingthe<code>dis_fd_depth</code>*M-function.*/privatestaticfinalMWFunctionSignaturesdis_fd_depthSignature=newMWFunctionSignature(0,false,"dis_fd_depth",5,false);/***Constructsanewinstanceofthe<code>dis_fd_depthclass</code>class.*/publicdis_fd_depthclass()throwsMWException{super(dis_fd_depthMCRFactory.newInstance());//addthistosInstancessynchronized(sInstances){sInstances.add(this);}}privatestaticMWComponentOptionsgetPathToComponentOptions(Stringpath){MWComponentOptionsoptions=newMWComponentOptions(newMWCtfExtractLocation(path),newMWCtfDirectorySource(path));returnoptions;}/***Constructsanewinstanceofthe<code>dis_fd_depthclass</code>class.Use*thisconstructortospecifyacomponentdirectoryotherthanthedefault*location.*@parampathToComponentPathtocomponentdirectory.*/publicdis_fd_depthclass(StringpathToComponent)throwsMWException{super(dis_fd_depthMCRFactory.newInstance(getPathToComponentOptions(pathToComponent)));//addthistosInstancessynchronized(sInstances){sInstances.add(this);}}/***Constructsanewinstanceofthe<code>dis_fd_depthclass</code>class.Use*thisconstructortospecifytheoptionsrequiredtoinstantiatethis*component.*Theoptionswillbespecifictotheinstanceofthiscomponentbeing*created.*@paramcomponentOptionsOptionsspecifictothecomponent.*/publicdis_fd_depthclass(MWComponentOptionscomponentOptions)throwsMWException{super(dis_fd_depthMCRFactory.newInstance(componentOptions));//addthistosInstancessynchronized(sInstances){sInstances.add(this);}}/**Freesnativeresourcesassociatedwiththisobject*/publicvoiddispose(){super.dispose();synchronized(sInstances){sInstances.remove(this);}}/***Invokesthefirstm-functionspecifiedbyMCC,withanyargumentsgivenon*thecommandline,andprintstheresult.*/publicstaticvoidmain(String[]args){try{MWMCRmcr=dis_fd_depthMCRFactory.newInstance();mcr.runMain(sdis_fd_depthSignature,args);mcr.dispose();}catch(Throwablet){t.printStackTrace();}}/***InstallashutdownhooktocalldisposeAllInstances.*/static{Runtime.getRuntime().addShutdownHook(newThread(){publicvoidrun(){dis_fd_depthclass.disposeAllInstances();}});}/***HelperfordisposeAllInstances.*/privatestaticdis_fd_depthclasspopInstance(){dis_fd_depthclasso=null;synchronized(sInstances){Iteratori=sInstances.iterator();if(i.hasNext()){o=(dis_fd_depthclass)i.next();sInstances.remove(o);}}returno;}/***Callsdisposemethodforeachoutstandinginstanceofthisclass.*/publicstaticvoiddisposeAllInstances(){if(null==sInstances){return;}synchronized(sInstances){dis_fd_depthclasso=popInstance();while(o!=null){o.dispose();o=popInstance();}}}/***Providesthemlxinterfaceforcallingthe<code>dis_fd_depth</code>*M-function.*@paramlhsListinwhichtoreturnoutputs.Numberofoutputs(nargout)is*determinedbyallocatedsizeofthisList.Outputsarereturnedas*sub-classesof<code>com.mathworks.toolbox.javabuilder.MWArray</code>.*Eachoutputarrayshouldbefreedbycallingits<code>dispose()</code>*method.*@paramrhsListcontaininginputs.Numberofinputs(nargin)isdetermined*bytheallocatedsizeofthisList.Inputargumentsmaybepassedas*sub-classesof<code>com.mathworks.toolbox.javabuilder.MWArray</code>,or*asarraysofanysupportedJavatype.ArgumentspassedasJavatypesare*convertedtoMATLABarraysaccordingtodefaultconversionrules.*@throwsMWExceptionAnerrorhasoccuredduringthefunctioncall.*/publicvoiddis_fd_depth(Listlhs,Listrhs)throwsMWException{fMCR.invoke(lhs,rhs,sdis_fd_depthSignature);}/***Providesthemlxinterfaceforcallingthe<code>dis_fd_depth</code>*M-function.*@paramlhsarrayinwhichtoreturnoutputs.Numberofoutputs(nargout)*isdeterminedbyallocatedsizeofthisarray.Outputsarereturnedas*sub-classesof<code>com.mathworks.toolbox.javabuilder.MWArray</code>.*Eachoutputarrayshouldbefreedbycallingits<code>dispose()</code>*method.*@paramrhsarraycontaininginpu

解决方案
解决方案二：
有人遇到这样的问题吗？
解决方案三：
未定义'dis_fd_depth'为输入参数的double型。楼主不急慢慢找
解决方案四：
请问在myeclipse中，java要调用matlab生成的jar包时，系统环境如何配置？详细说明一下，谢谢了！
解决方案五：
我觉得，matlab帮助说得还是挺清楚的

在web中如何配置matlab环境，报错：java.lang.Exception:Failedtofindtheruntimelibraries,requiredbyMATLABBuilderJA,onsystempath
解决方案八：
未定义'dis_fd_depth'为输入参数的double型。楼主不急慢慢找，这个只有你自己能帮上你。
