Overview

The list below presents highlights of the functional coverage NI LabVIEW MathScript provides.

LabVIEW MathScript is a textual math component of LabVIEW that works with more than 800 textual functions for math, signal processing, and analysis. In addition, you can use more than 900 graphical functions for signal processing, analysis, and math that are available as VIs (programs) within LabVIEW.

The list below presents a summary of the functional coverage LabVIEW MathScript provides. New functions added with LabVIEW Version 8.6 are bolded.
