Inquiry - What is your Modularity Index?

[Jarrod_S.]

That's funny. My project has a modularity index of 0. But that's because everything I write goes into vi.lib and doesn't count as a user VI (of which I have none)!

LOL i was wondering where is the little man inside the bachine box

[Graziano]

bachine box?

[Wiebe@CARYA]

Just a question...

Modularity Index = (# user VIs   /    total # of nodes ) *
100

Is the # user VIs the recursive number, or just the subvi's directly in the
main? The metrics tool only gives the recursive number?

(If I use it on my Main vi, I get 338/53*100 = 638 )

Regards,

Wiebe.

I started to write a VI to calculate this, but determined this is a recursive problem and don't have time to work on it.

I've posted the VI here if anyone is interested...

For my largest project, I got an index of 1.92... BTW, I'm using LV 8.2 and found the tool in Tools\Profile\VI Metric...

I guess this says I should be more modular, but I like my style!!

Hi Wiebe,
   I suppose it is meant to be recursive, ie the total number of subVI in  your project, excluding vi.lib files.  About vi.lib, you can include them if you heve developed then, maybe, it'd be interesting to get the opinion from Peter Blume... it imagine 638 is quite an high index....

   Have a nice day!

Hi Phillip,
   can you post that VI for LV 7.1? If it doesn't take too much time.... thanks!

GerdW,

You can read about VI Modularity Index in the sample chapter from "The LabVIEW Style Book" located here (see page 13).

Graziano, I've updated the post to include a 7.1 version.
