Using Java API gives "no nativemvm in java.library.path"
显示 更早的评论
I am attempting to work through the example code for the Java Matlab engine API (Note: this is calling Matlab FROM Java): https://www.mathworks.com/help/matlab/matlab_external/java-example-source-code.html
I can get to the last step, then I get the error: "java.lang.UnsatisfiedLinkError: no nativemvm in java.library.path". FYI I get this same error when trying to run my own code linked to Matlab in Eclipse.
Does anyone know how to fix this? Or know of any other information/examples/tutorials on calling the Matlab engine from Java? (This is a very new feature in 2016b so there is not much information out there)

I am having the same problem. I have added the matlabroot/bin/maci64 to both the PATH and DYLD_LIBRARY_PATH and am getting the same error: no nativemvm in java.library.path. It seems like people have been able to get this to work by adding to the PATH in Windows. Has anyone had success on a Mac?

Can you show me , any of your codes ? @Jim Person
import com.mathworks.engine.*;
public class CNN
{
public static void main(String[] args) throws Exception{
MatlabEngine eng = MatlabEngine.startMatlab();
double[] a = {2.0 ,4.0, 6.0};
double[] roots = eng.feval("sqrt", a);
eng.close();
}
}
I was trying to compile that code which is an example from mathworks but Eclipse says that it has an error in feval function due to th arguments that Im using

This also worked for me, but I had to first exit and restart my IntelliJ IDE after changing the PATH on the Windows Environment Variables

I still have this problem (also with IntelliJ IDE) despite changing the PATH on the WIndows Environment Variables. Could you please explain hoe you were to solve this issue step by step? It seems that I am missing something here. Thanks!

you need to add the matlab library to your IDE(eclipse or others) or System (if you don't use any IDEs ), see below:
that's the right solution.

I'm having the same problem but can't find the solution for it.
I added the path to my PATH variable and added the engine.jar to my library but stil it gives me the "no nativemvm in java.library.path" error.
Can someone explain all the steps he took to get it working? Is it important where the engine.jar file is located or can i put it in the working directory of my project?
I'm using osx with netbeans and downloaded Matlab R2017a.

This is a quote from the file "<matlabroot>/extern/examples/engines/java/README" for Mac:
Run the examples by adding "<matlabroot>/bin/maci64" to the Java library search path without setting the DYLD_LIBRARY_PATH variable:
java -Djava.library.path=<matlabroot>/bin/maci64 -classpath .:<matlabroot>/extern/engines/java/jar/engine.jar EngineConsoleDemo
