    If you're running a un*x box you can run 'patch' to do the job (also see "man patch"). The patch program takes a diff file (the thing you dispayed) and a source file and applies the patches listed in the diff file to the source file; if you don't have patch available you can always apply the patches manually (just edit the source file). - means delete the line, + means add the line. Also google for "unix apply patch" for the exact syntax of diff files.

    kind regards,

    in unix there is a patch command, likely if you are in the top level folder
    Java Code:
    patch -i the_patch_file.patch
    Eclipse IDE supports applying a .patch file to a project, but this requires you to have the sources set up in a workspace, which can be a pain if you don't already use eclipse.

    in this case, you could just open up this, go to line 214, and comment out

    matlab.fevalConsoleOutput(command, args, 0, null)

    and adding after it

    matlab.fevalConsoleOutput(command, args);

    You would then need to rebuild these java sources, such as using what ever instructions were given with this package. Most projects now use ant or maven tools for this. hopefully there is instructions for doing this.

    I've written applications that interact with matlab via Runtime.exec. Matlab has a terminal mode that facilitates piping information back and forth via stdin/stdout. This is handy if you need to run a filter design tool or something like that and want to interract with the results.

    Matlab also has direct Java support built-in, so you can instantiate a java object from Matlab and interract that way too.

    Default Java API to call MATLAB from Java

    matlabcontrol is a Java API which makes it very easy to call MATLAB from Java. It can do everything the MatlabControl class can and do more, including controlling MATLAB from a Java application running outside of MATLAB. Using the API is as if you were interacting with MATLAB's Command Window, and you can retrieve the results as Java objects. To get started, take a look at the walkthrough.
