Using Cobertura 1.9.2 with JDK 1.6.0_14 raised the following exceptions:


Exception in thread "Thread-0" java.lang.ExceptionInInitializerError

The newer versions of Cobertura fixed this issue!

Today i had to access a matlab script from a java program. After some hours of trying to get it work by using matlabs command line i found a method to call a matlab script without using the command line. Using matlab -r “functionName” didn’t work because of some unknown charset erros i haven’t found till now. The basic idea is based on this blog-post.

Therefore, a process must be created:


String command = "matlab -nosplash -nodesktop";
Process process = Runtime.getRuntime().exec(command);


Afterwards we obtain the standard-input of the process and send a command to be interpreted by matlab:


BufferedWriter out = new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
out.write("function_to_be_executed");
out.write("\n");
out.write("exit;") // this will close matlab after the execution finished!


If you like to see what is happening, try to read from the process.getInputStream()

hope that helps some of you!
