How to subtract ith position of one array from the ith position of another

Hi, everyone,
In my program, I subract one array from another. It should be like X(i) - Y(i)
Can someone explain to me how I can make sure that I'm subracting ith value of array 2 from the ith value of array one? Not , for example, X(i)- Y(i+1)?
Thank you
Solved!
Go to Solution.

Hopefully, you are not doing anything more complicated than this:
This does X(i) - Y(i).

How can I select more than one song from the search results?

I want to create playlists based on certain words in the song title. For example, I may want to create a playlist of all my songs with LOVE in the title.
Doing the search is easy, but I can't select more than one song at a time. Is there any way in iTunes 12 for Windows to do this? I found an answer in iTunes for Mac, and it basically says to "un-check "Search Entire Library." " but I don't see that option in iTunes for Windows.
Here is the link to that question: how can i select more than one song from drop down search bar
I hope some Windows user can help me out.

Found the "Search Entire Library" option - click on the small (VERY small for my eyesight) down arrow next to the magnifying glass. Also need to select "Filter by: Songs", and then the songs in the main window show the results.
I'm going to leave this up on the board because 1) in case someone else has this question, and 2) I don't know how to delete it anyway.

You do not need to install iTunes twice.

How to call BSP page in one frame from a webdynpro page in another frame?

Dear experts,
I have a scenario as follows:
A BSP application which contains 5 frames. in the first frame I am calling a web Dynpro application. This is a tree and it is displayed correctly. on click of an item (node item) in the tree, a bsp page should be displayed in the second frame. I am not able to display this in the second frame. When I call the BSP page, it is getting displayed in the same frame (i.e, the first frame).
Kindly help me out.
Thanks & Warm Regards,
Jenny

From WDA you can't force the navigation of a different frame. Nor should you really be building an application with WDA running within a frame. You will have session management problems.
SAP recommendation is to use the NetWeaver Portal. You could then place the WDA and BSP applications into separate iViews. They can communicate with each other using Portal Eventing.

How do you change a multi page document from the default black to another colour?

I have a multi page calendar chart that is black text and lines in InDesign. I need to print it as green on a copier not press. Is there a way to change the black to green without having to go through each text box and line separately?

I hope you are using paragraph styles. Change the color there and it will change everywhere you have used this style. If you have set up your styles correctly you need to change one styles and alll others will chage too.
Never use a character in InDesign without a Paragraph Style.

HT204053 how do i change my icloud email address from the one i already have input?

how do i change my icloud email address from the one i already have input?

Hi sparkie,
You cannot change your iCloud email address. It is an @me.com address, and is associated specifically with that iCloud account. If you want a different @me address assigned, you have to delete the current iCloud account and set up a new one.
Here is a link with all the support information for iCloud:

Hope this helps!
