Re: octave in java

[Ernst Reissner]

additional information:

If i try the following java code:


   public static void main(String[] args) throws Exception {// NOPMD
System.load("/home/ernst/Octave/octave/.build/libinterp/.libs/liboctinterp.so");
    org.octave.Octave o = new org.octave.Octave();
    System.out.println("need threaded invocation: "
               + o.needThreadedInvocation());
    o.doEvalString("sin(42);");


this results in


need threaded invocation: true

Process eu.simuline.octave.OctaveInterfaceTester aborted

so needThreadedInvocation() can still be invoked whereas doEvalString
can not.

Even o.doEvalString("42;");


does not work.

Any suggestions?
