Details

If you call this function from a MathScript Node or a user-defined function, a warning glyph appears on the MathScript Node frame. The warning glyph indicates that LabVIEW operates with reduced error checking and slower run-time performance for the MathScript Node. To improve the error checking and optimize the performance of the MathScript Node, remove this function from scripts and user-defined functions. Also, do not change the MathScript search path list at run time. Instead, use the MathScript: Search Paths Options page to configure the default search path list.

This function is not supported in the LabVIEW Run-Time Engine. Do not use this function in a stand-alone application or shared library.

Examples

A = 12*23+4i
B = 4
clear A
A+B
