Hello,
You need to have a licensed copy of The MathWorks, Inc. MATLAB® software version 6.5 or later installed in order to use the MATLAB script node. Unfortunately, I do not know of anything like a MATLAB runtime engine. However, introduced in LabVIEW 8.0, the MathScript node may be able to natively execute your particular scripts. It uses a syntax that is generally compatible with the MATLAB software. LabVIEW 8.2 added support for the MathScript node in the application builder so you can deploy your applications to PCs that don't have a version of LabVIEW installed.
