hi, did you solve the problem? MWCellArray Rulelist_Jtable=new MWCellArray(49,3); for (int i=0;i<val.length;i++){ for (int j=0;j<val.length;j++){ Rulelist_Jtable.set({i,j},val[j]); } } Myeclipse points out that the method set(int[],Object) is of wrong using with the parameter 'Object'.

Hi all: We are trying to run a java program calling Matlab. When we run our program, we get the following error: Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to find the library libmwmclmcrrt.7.10.dylib, required by MATLAB Builder JA, on java.library.path Therefore we proceed and add the following VM argument: -Djava.library.path=/Applications/MATLAB_R2009a.app/bin/maci/ Now we get a different error: Exception in thread "main" java.lang.LinkageError: dlopen (/Applications/MATLAB_R2009a.app/bin/maci/libnativemcl.jnilib, 9): Library not loaded: libt...

Hi guys I am now experencing a great difficulty in the interation between java and matlab. I have an objective function written in JAVA with has method return an numerical number, i call it 'profit'. The nature of this obtive function (ObjFun.java) is that it takes an parameter input, say C, with different C value, the returned profit value is different. Eventually I want to find the optimized C value which produce the maximun profit (C will be under constrains). Initially I want to use linprog or fminsearch in matlab. So I tried the command in matlab that excutes my ObjFun.ja...

Hi all, I am having trouble getting the return value from matlab to JAVA. I have tried Kamin Whitehouse 's code(matlabcontrol.java) and get working for eval and feval, but having trouble using blockingFeval function which returnts the value of matlab. The problem I am having is it returns some value valid only in matlab workspace and when I play around with the return value in matlab, it works fine but in Java program it is just junk data. I corresponded with Kamin and he thinks that jmi.jar has been changed since he developed the class. The matlab library now returns the handle of t...

Hello, Does anybody has any idea how to update Matlab function about Java object change ? It could be done by polling: while JavaObj.getValue()=='not done yet' pause(1); end But polling is evil. There should be more elegant way to do this job ... I've checked 'Matlab Java Interface' docs : http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/f6671.html , but found nothing on the subject :( Thanks in advance for your help, Could you use javacomponent to set up the object, and set a callback to repond to the changed value?

Hello, I want to know if there is a way to call matlab from java (in windows), but not by calling the java code from matlab. I want to use a different JVM than the one matlab uses. In linux it is simple since I can use input/output redirection, is there a way to do this in windows (I have matlab 5.3, pretty old version). Thanks a lot, Nili. ...

Hi, I found that there are some GUI windows in Matlab 7 return Java objects directly instead of returnning figure handles or object handles. I want to delete them, but I tried "delete(handles.objJava)" where objJava is some Java object returned by these Matlab GUI windows..., I saved it to handles as a field... but it did not work. The error message is: ------------------------------------------ ??? Invalid handle object. Error in ==> ieMyProgram>myCallbackFcn at 162 delete(handles.objJava); ...

Dear all I need some help about using Eclipse RCP with MATLAB. I want receive input variables from web (probably using Eclipse RCP, I just heard about Eclipse RCP) and calcuate something and generate figure or animation in MATLAB. Finally, send the result to the web and display them using Eclipse RCP. I know about MATLAB Web Server (MWS). However, MWS has some limitation, so I want to combine Eclipse RCP with MATLAB for more compatibility. Could you help me ? The example will be greate help for me. Thanks in advance. ...

Hi guys. I really apologize for asking this question, since I'm sure it is either basic or not possible, but I have been reading through the documentation and can't seem to figure this out, since the examples look like they just send and receive variables from the Java methods. Could anyone give me a short example of how to call a method from a Java object that causes some sort of action to be performed in MATLAB? For example, I would like to: 1) make a new object of MyClass from MATLAB called MyObject. 2) run MyObject.DoSomethingInMatlab() 3) have a statement in DoSomethingInMatlab...

I have written an application in Matlab and compiled it into Java code using the JA builder. I'm really stuck from here as to how to integrate it into my application.

Hi This maybe sounds a little bit weird, but I'd like to use java components which themselves call Matlab Builder JA classes from within MATLAB. So... 1. Write .m code and compile it with the Builder JA 2. Write java code, which uses the JA classes 3. use the whole framework from MATLAB This approach would represent a very flexible framework for our data analysis, with data analysis, visualization and speed optimizations on both sides (JAVA/MATLAB). Up to know the framework works well if I stay on the java side and use the Builder JA components from within java. In MATLAB I can...

Hello All I am trying to call Matlab from java. I am using Brad Phelan's matlab snippet http://xtargets.com/snippets/user/bradphelan/tag/feval to investigate how to do this but all I get is matlab showing "Busy" and basically hanging. I have tried commenting out the semaphore control which "helps" but I then get a null exception because the return value is null. I call my test routine from matlab as follows: TestMat.main({}) My test routine looks like Brad's example: public class TestMat { public static void main(String[] args) { MatlabFunction&l...

Hi everybody! My problem can be described as follows. I have a tool in Matlab that requires calling an optimisation algorithm in C. This algorithm consists of several C-files, one of which contains the function to be minimised (CFUNCTION), and another is the main algorithm file (CMAIN). Now what I want to do is to call Matlab from CFUNCTION or CMAIN and specify my custom function (MFUNCTION) to be minimised. So, I'm calling Matlab from C from Matlab. I'm a newbie in C and MEX files. Should I rewrite CMAIN as a MEX file and include CFUNCTION in this and then use mxCallMATLAB? Or can...

I used the MATLAB R2010b Builder NE to compile a COM-DLL (a single class with a single method) and intend to call the method from within MATLAB R2007b. I cannot distribute m-files or p-files because my code uses new object oriented features introduced in R2008a. So the idea is to install Matlab Compiler Runtime 2010b on the target machine in addition to MATLAB 2007 and access the function from a DLL. Unfortunately, I was not able to run the method from within MATLAB and could not find any documentation on how to use MATLAB to "test" COM DLLs (or even .NET DLLs or C-DLLs) built with the MATLAB Compiler. The documentation yet is very clear on how to use external interfaces, e.g using actxserver() for COM DLLs, or NET.addAssembly() for .NET DLLs or loadlibrary() for C-DLLs. Since I have no installation of R2007 right now I did everything in R2010 (compiling and testing). Here is what I tried for COM DLLs: >> p = actxserver('myComponent.myClass'); >> p.myMethod(0,[],[]) ??? Invoke Error, Dispatch Exception: Source: myComponent.myClass.1_0 Description: MCR instance is not available and for .NET DLLs: NET.addAssembly(fullfile(cd,'myComponent.dll'); >> p = myComponent.myClass(); ??? Message: The type initializer for "myComponent.myClass" threw an exception. Source: mscorlib HelpLink: and for C-DLLs >> loadlibrary('myComponent.dll','myComponent.h'); Warning: Warnings messages were ...

I'm making an end-user application where I would like to use Matlab functionality both for calculation and plotting. Matlabs GUI builder guide does not satisfy my needs (no support for f.ex. internal frames and other nescessities), so I'm planning to compile my Matlab code and use other API (Java, QT or something) for GUI. My problem is then, that I loose access to the neat plotting commands availible under matlab GUI... Is there a way of integrating Matlabs plot functionality into another GUI system? - has it been done? - I appreciate any response! - P�l Berge ...

Hi all, I'm going to work on a project involving a parallel version of MATLAB - I'm aware of various efforts like MATLAB-*P and so on Right now I need to read up on some material regarding MATLAB internals eg: How are the ATLAS(or is it BLAS) routines called in MATLAB? How does MATLAB's C code store information in memory, cache'ing etc? How is one to get at those? Do you know of any suitable reference(s)/resource(s)? Thank you very much, Aravind ...

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

Some time ago I came across a Matlab Webinar titled :"Deployment of Matlab Applications to C/C++ COM and Java" where mention was made about the "Matlab Builder for Java" product (or option?). If I got it right this Builder would be something to appear in a following release of the Matlab Builder (formerly Compiler). So, the question is: where is it? Is it included in R14? Is it a dead project? It would be great if someone from TMW could share some info on this subject.. Apparently many people's projects could be simplified if this product was available (or was to become...
