I was hoping to read and write variables from the Matlab workspace. Can I do it? If so, how?

    VisSim provides Matlab read, write and function call blocks. These blocks allow reading and writing to the Matlab workspace. Normally the Matlab blocks are installed if the VisSim install detects a prior Matlab installation. If this is not the case, then

    1. Download vsmML.DLL to your computer
    2. Copy vsmML.dll to the DLL directory of your MatLab installation
      • This is the directory that contains the libeng.dll and libmx.dll. In older installations they are in the same dir as matlab.exe (/bin). In new installations it is /bin/win32 or /bin/win64.
    3. In VisSim, go to Edit > Preferences > Addons and add the path to the DLL that you copied in 2. to the addon list.

    Greetings,

    I just did the procedure described above and I'm getting an error that says something like:

    • Matlab interface error 193 %1 is not a valid Win32 app;

    The MATLAB version is 7.8.0 64 bits and Vissim's is 8.0C0.

    I'm just wondering if it's something related to x64 version of MATLAB...

    Thanks in advance.
