if you're tried making an .exe from a vi with a Mathscript node with Application Builder 8.2,
you discovered that (surprisingly) the Mathscript node is being converted to G code.
This was particularly obvious when I made a simple executable that ran
a modified Cholesky algorithm in the Mathscript node. Numerous linear algebra vi's
that were not on the block diagram were included in the slow build.
So, for Mathscript to support sparse matrices, LabVIEW will probably have to support
sparse matrices first. I imagine they are working on it as we speak.
But in the interim, attached is a first start: a tri-diagonal matrix solver
using the fast Thomas algorithm.
