ISC Ltd. w/ Houlder Ltd. Dr. Andy Clegg, Lead Engineer & ISC Managing Director: “We used the LabVIEW MathScript RT Module to run a textual node containing our m-file code, developed with MATLAB on a desktop, for kinematics on the real-time CompactRIO controller. MathScript has significant benefits for real-time deployment on the CompactRIO controller including determinism, easy debugging, and no extra compilation steps.“
