Running a Matlab .m file for data export

[Mattm]

I remember a while back looking into exporting data into a Matlab
session using a .m file. I'm trying to re-create that, but can't find
my notes on it. I thought I remember someone from symvionics writing
something up about that, but I couldn't find that out on the website.
I remember having to specify the .m file in the propertybag column of
the datagroups table, but I also remember something about an Iadsread
or something like that, to read the data into the session. Am I
close, or has Alzhemiers already set in.

Hi Matt,

Search for "Data Group Setup" in the help file. The Matlab export options
are there. The one you're interested in is "MatlabExportMethod=MatlabFIle".
If you want to export directly to Matlab, you don't need to specify the file
option. By default, it will inject the data directly into Matlab upon
export. You can also export all your data to Matlab and then write out files
from within that environment (save basically).

The iadsread method is a much more direct route. You can "pull" data
directly from Iads data files (and any derived parameter defined) into
Matlab via a function call. All you have to do is specify where your data
resides, the parameter list, and start/stop times (or number of points).
Read over the "HowTo.m" file in the C:\Program Files\IADS\MatlabExtension
directory. It will explain how to use the mex function/dll. It's much faster
than exporting to a file and allows you to stream over the entire flight
without the need to load the entire area of interest into memory at one
time.
