Does spline-interpolation work? (what's it supposed to do?)

Hello!
      I was told (by a co-worker) that Spline_Interpolation[Xi] should exactly match a "tabulated" Y (input) if Xi was one of the "tabulated" X input values.  I don't know if this is correct - if it is, then the function isn't working as expected.  Any insight is appreciated.
Thanks in advance!

Hmm...  I think the X and Y are right, but wiki says X is supposed to be increasing and in the VI above, X is decreasing.  After reversing X-array, exact Y values show-up as expected - excellent!  I'll cautiously-consider this is the cure.
You got me to focus on getting inputs correct,
thank you Matt!

  • ITunes keeps freezing no matter what I try. No that it controls all my music, and doesn't work, what am I supposed to do?

    It seems that iTunes doesn't want to work. I've reinstalled, ugraded and restarted my computer. But nothing seems to work iTunes keeps freezing. Now it's just a useless app on my computer. It controls all the music and it's taken many hours to be bothered to use it, now that I depend on it it doesn't work. Is there another more reliable program that organizes and transfers music to iPods? Or am I just stuck with the music thats on my iTunes?
    I'm not really impressed and that my family has many apple products that are mainly run by this one piece of software is mind bogglling.
    Are there older versions of iTunes to use? because before this last update I had no issues.

    If you mean that Find My Phone is asking for a password to a different Apple ID to your current Apple ID and that ID is a previous version of your current ID, not an entirely different one.
    The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID using your current password, you don’t need access to this address if it’s previously been used with your Apple ID, once you have saved these details enter the password as requested on your device and then turn off "find my phone" and delete the account from your device.
    You should then change your Apple ID back to its current state, save it once again and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again.

  • I am having trouble with my iPad, i can start it, but the iPad does not work. i tried to use the power and home button at the same time, the apple logo appears, but the iPad does not work. What am I suppose to do?

    I am having trouble with my iPad, i can start it, but the iPad does not work. i tried to use the power and home button at the same time, the apple logo appears, but the iPad does not work. What am I suppose to do?

    After the Apple logo appears, what happens then? Can you hear any sounds or if you tap on the screen, does it seem like apps can open or are you just seeing a black screen? You might have a hardware problem, but you can try restoring the software and see what happens.

  • To what extent does auto-syncing work...?

    I have researched this but can not find the answer anywhere.
    I need to know to what extent does auto-syncing work?
    I started my library quite some time ago, and I didn't want to use the auto-sync feature. My library has grown very large and to be honest, I still wouldn't mind doing the manual syncing if my behavior and/or needs hadn't changed. However, I am now going back and adding artwork and making some slight modifications to several songs. Overall, through one type of change or another, this will affect the vast majority of my library. What I need to know is if I were to make info-related changes, will the syncing make the modifications on the ipod, or will they be ignored?
    For instance, here are some of the types of changes that I am beginning to make:
    - Adding Artwork.
    - Changing a track name from "Living in a box" to "Livin' in a box"
    - Adding info to the various fields such as album author, comments.
    - Modifying a track name from "Love is a Battlefield" to "Love Is A Battlefield"
    - Changing an album name from "Miami Vice Soundtrack" to "Miami Vice [Soundtrack]" or "Shrek (Soundtrack)" to "Shrek [Soundtrack]"
    - Updating an artist's name from "Jackson Five" to "Jackson 5"
    Any insights would be most appreciative.

    While in Manual sync, any changes you make in iTunes will not get put onto the iPod until you drag the songs over.
    Any changes you make on the iPod thru iTunes will not be on the original in iTunes.
    Any rating,
    Any reason you are using manual sync instead of Auto sync?
    If you don't want (or can't) to put everything in iTunes on the iPod, use selected playlists and manage those playlists.
    When you make changes to the songs in iTunes, they will get updated onto the iPod automatically.

    If you can't enter the passcode then you have to place the iPod in recovery mode and then restore the iPod via iTunes. For ecovery mode see:
    iPhone and iPod touch: Unable to update or restore
    Note that this requires using the sleep/wake button.  If you are not successful then there is nothing else that I know you can do.

  • Hi, my apple ID verification email does not contain the link for me to click in order to verify my account. Re-submitting has not worked, what can i do to verify/activate my account

    Hi, my apple ID verification email does not contain the link for me to click in order to verify my account. Re-submitting has not worked, what can i do to verify/activate my account in order to access Icloud?

    If you want to change your iCloud ID or password on your phone go to Settings>iCloud and tap Delete Account, then sign back in with your updated information.  Note: this only deletes the account and any synced data from your phone, not from iCloud.  Provided you are signing back into the same account and not changing accounts it will be synced back to your device when you sign back in.

  • On PowerBook G4 OS 10.5.8 my chess App tells me "You can't open the app 'chess' because it is not supported on this architecture. It has worked before. What does that means? What can I do to get it working?

    On PowerBook G4 OS 10.5.8 my chess App tells me "You can't open the app 'chess' because it is not supported on this architecture. It has worked before. What does that means? What can I do to get it working?

    It sounds like you might have accidently copied Chess over from an Intel Mac, or an Intel Mac's installer DVD.  The architecture typically means it is designed uniquely for either Intel or PowerPC.  Be sure to extract Chess from the 10.5 Retail installer disc that looks like * and not any other disk.  http://www.charlessoft.com/ 's Pacifist lets you extract individual applications from installers without having to reinstall everything.

    Lighting effects in Photoshop CC doesn't work for me ... just shows ALL black .. any advice to get it to do what it is supposed to?

    So, you're totally new to computers?
    Go to the Help menu in Photoshop and select the System Info menu item.  Copy all that information and paste all of it here MINUS your serial number.
    Yes, Photoshop can delegate a lot of the computing tasks to the GPU on your graphics card.  You may have to disable that feature in Photoshop Preferences > Performance.

    Install Snow Leopard on another boot partition, or upgrade Microsoft Office to a newer version, or use any number of better alternatives. Some of them are free.
    Consider
    LibreOffice (donation-supported)
    NeoOffice ($10)
    OpenOffice (completely free)
    In addition to the above I also recommend Apple's Pages ($19.99). I use OpenOffice and Pages and have been completely Microsoft - free for over a year now. Life is better without Microsoft.
