17 How it Works: Using Scilab Scripts within LabVIEW

1. Install Scilab 4.1.1 or later, LabVIEW 8.0 or later, and the freely downloadable gateway 2. Open LabVIEW, create a new LabVIEW VI, and insert a Scilab script node on the VI block diagram 3. Enter your Scilab script in the Scilab script node 4. Right-click the Scilab script node border, select Add Input or Add Output, and enter input / output variable names 5. Connect LabVIEW wires to the new inputs and outputs

When you run your application, LabVIEW invokes the Scilab engine to execute your script
