how to get the coordinates of the highest value element in an 2D array

[sampath93]

i am working on a project in which i am trying to find the coordinates of the highest element of that array ...please help

Use Array Max & Min.  I'm pretty sure it only accepts a 1D array though, so you will want to put it inside of a FOR loop.  Autoindex on the rows on the 2D array and then do some comparison to see if your new Max is greater than your old max.

[RavensFan]

Reshape your array to a 1-D array and search for the max.  Now you have the coordinate you can do some basic math on to get back to the original row and column location.  (Remainder and quotient function would help here.)

indexes?  Nice one.  Indices is so old-fashioned these days...

Thanks for the replies but what exactly i asked was, for example if an 2D array  having 16 elements (i.e. 4*4)  and the greatest number of all the 16 elements is located [at lets say @ (3,2)] ,then my final out put should show me the column number and the row number

That is exactly what the snippet posted by Darin.K will provide. Try it.

I wasn't sure it would take a 2D array and didn't have a way to test it earlier.  Glad to see that it does.

Not that I claim this site to be fact, but it states both are correct, but one is more common in America vs other English

Personally I prefer Indices, but what ever.

Eh, it's just so they don't have to write "Index/Indices."  So much more efficient to put "Index(es)."

edit

I like "indices," myself.  It rolls off the tongue so much more smoothly.

I did the same thing as your question. My solution is:

- Reshape your 2D array to become a 1D array, for ex: your 2D is 4*4 and 1D reshaped is 1*16
- Use array Min and Max to find out Max value and Max index.

- Assume that your Max index is 10 = 4+4+2 so it means your coordinate of the Max value is (3,2)

Hope that my answer can help you.
