B Spline Fit Lockup

Hello

I've implemented the function B-Spline fit to find a curve of standardization. With specific sets of data, the program is suspended in the call from the library of NI_AALPro.lvlib:B - Spline Fit _nD .vi and ctrl alt del is the only way to escape. After you change the order of the polynomial fit or the number of control points he is still hindering on the data set.

I'm under Labview 2009 with the complete development package, version 9.0f2.

What is a user error? If not, does look like a bug in the routine curve? And nobody knows how to identify a problematic set of data before the interruption occurs?

Attached is a sample of code with a data set that causes labview to lock up, so make sure that you have saved if you run!

Thanks for the research!

I looked more closely at your last 2 points of data and discovered that they have the same x value. By changing the last x don't value to the 6th decimal no hang up occur.

    Hello

    I have a curve I need to straighten, and so I decided to use the cube to adapt, but I need all the points of origin of the interest. When I tried the cubic Spline adjustment function in LV, I had a smooth curve, but it did not contain the first points of interest.

    I read in the literature that, with cubic splines a smooth curve can be adapted on the original points, would like to know how this problem could be overcome.

    The original curve and the fitted curve are fixed below

    What you should do is interpolation instead of editing.  Two ways to do it.

    1 use the Interpolation Spline VI

    2. set the smoothness to 1 for all points of adjustment of Spline cubic

  • Data smooth XY of a closed curve

    Hello. I'm looking for suggestions on how to smooth the XY data that resembles the Attaché, a closed curve. The filter screw I looked all use X but not of X and Y.

    Thank you.

    Have you tried either:

    (a) using B-Spline Fit?, or

    (b) smoothing X and Y separately and recombine to give your smooth curve?

    You can duplicate your data in the adjustment so that you get a more continuous curve at the ends.  Here's a quick, rough example:

  • Interpolation spline work? (what is it supposed to do?)

    Hello!

    I was told (by a work colleague) [Xi] Spline_Interpolation must exactly match a Y 'paintings' (entry) if Xi was one of the 'paintings' X input values.  I don't know if it's okay - if that's the case, then the function does not work as expected.  Any idea is appreciated.

    Thanks in advance!

    Mathematically, the way that the work of interpolation spline is that it fits the curve so that the adjusted data pass through each point of experimental data.  This is in contrast to the linear or polynomial curve adjustments, which reduce to a minimum the overall error.

    One thing that you * could * be done wrong reverse x and are data.  Can not look at your code right now.

  • The spline graph?

    Anyone know if it is possible to create a chart "spline" in JFX: http://www.fusioncharts.com/demos/gallery/#spline-and-spline-area

  • Watch OS 3 - current fitness activity closes - Bug?

    When you use the market activity (with an open goal) the session closes halfway through without my intervention.

    Today, I came home after a 5km walk to find that the session had stopped smoking. When I opened it the activity app, it showed summary screen activity completed with 0.19 km of distance.

    This is the 3rd time that to happen - it's a new feature or a bug?

    Hello

    Make sure the wrist detection is open (on your iPhone, in the application of the watch, go to: My Watch (tab) > General > wrist detection.)

    Follow-up may be affected if your watch loses contact with your skin, leading them to believe that he had been removed from your wrist. A bunch of cowards can trigger this by allowing your watch raise your wrist or clothing (for example, the end of a handle) to fit under the back of the watch. Performance of the sensor can also be affected by temporary or permanent changes on your skin, such as certain wrist tattoos.

    Also check the back of your watch is clean and dry (use an abrasive, lint cloth).

    During the year, Apple Watch should be worn comfortably on top of your wrist. Apple suggests that you consider your clamping Strip before workouts and it loosen again thereafter. Better contact with your wrist can also improve the performance of sensor of heart rate during your workout.

    Workouts also can be suspended or ended early because of accidental interaction with the screen of the watch (including clothing). To avoid this, you can lock the screen during training (see article to drive app for instructions).

    If I use the fitness app in shape and choose 'Other' for my workout, it shows my heart rate. But if I select 'Run in the open air' or "Walk in the open air" it does not show it.

  • Apple Watch Fitness?

    Hey guys! I thought that if I would like to pre-order the Apple Watch 2. But I just have 1 question. The ability of Apple Watch will always be on, followed everything I do? As he count me walking on the refrigerator and that count for the discount shaped daily "report"? and also me being at the Mall, do the basic everyday things, will it count fitness report and tell me how many calories I've lost that day? I really want to know this, because I want to start making goals so I can begin to be more active.

    So in summary, I just want to know if the ability of Apple Watch is always enabled, counting of the basic daily activities and tell me how many calories I've lost that day?

    Thank you.

    Hello

    The activity app works continuously in the background, tracking of activity including the measures taken and Active of Calories burned.

    It also monitors your progress toward your three daily goals: Move (Calories active), exercise and support.
