Problem in curve fitting and or forecasting decay

[slipstick]

Hello,

I have a bit of code that I want to use to fit a curve and forcast the future points, but I can't make it work with the timestamp I need. Any help would be appreciated! Labview version is 2009 SP1.

From looking at the code (not trying it yet), I suggest you convert the timestamps to DBL instead of U32 and set the initial time to t=0 by subtracting the first element from the array.

changing to DBL was a good idea. Haven't gotten the rest working yet.

One of our engineers took pity on me and came up with this. Does just what I need. Thanks for looking at it Darin!

• Is there any conceivable reasons for your three sequence frames????
• You leftmost FOR loop can be removed without change in functionality.
• ...

OK, this code is pretty ridiculous, why would you need to loop and constantly compare to find the 0.6 threshold if you can calculate the corresponding time from first principles using the best fit values?

Here's a very quick draft showing some simplifications. Many more simplifications are definitely possible (I kept most of your code intact so far).

The sequence frames are temporary. I use them to keep the code organized and grouped by function while I am coding (the auto cleanup tool lays things out better with them). I'll delete them before final use.

I'll look at the loop. Right now I don't fully see how the removal wouldn't change it. (Homework, I guess.)

Thanks for the changes. I'll have to look that over. I don't understand this kind of math or stats at all. All new stuff.
