How can I parse mathematical expressions in LabVIEW?

Solution

There are a variety of tools for parsing mathematical expressions in LabVIEW. Three possible routes are listed below.

The simplest and most accessible functions in LabVIEW are contained in the 1D & 2D Evaluation VIs. These VIs can parse functions and evaluate them at multiple points as defined by the user.

For parsing more general/complex functions at a single point, LabVIEW has the Formula Parsing VIs. There are three such VIs:

Parse Formula Node: This function cannot parse formulas dynamically, but it can parse static formulas declared in the node prior to run-time.
