Hello,
Both the MathScript node and the MATLAB® script node are present in the LabVIEW 8.2.1 student edition and the evaluation version -- no download is necessary. The MathScript node can be found on the Programming >> Structures palette and the Mathematics >> Scripts & Formulas palette. The MATLAB script node can be found on the Mathematics >> Script & Formulas >> Script Nodes palette.
You can download an evaluation version by going to www.ni.com/labview and clicking on "Test-Drive LabVIEW"
