Version 5.1 of LabVIEW instroduces a Matlab script node that allows
for you to import or type Matlab scripts into the formula node, and
at runtime, LV will use ActiveX to pass data and the script to Matlab,
get the script processed by Matlab, and return the results to LV.
It is also possible to use ActiveX to do similar ope
rations without
using the new node. As for whether this is in realtime, it depends on
what you mean. This will be two applications communicating over RPC
wrapped in COM and going through ActiveX Automation. It will be
reasonably predictable as to how long the computation will take, and
it will be faster than sharing data between the products using file I/O,
but it will not be small in size or blazingly fast.
