Finding Values in a "Matrix"

I have a matrix I have created in Excel. I am using this for correlations.
I have cells B1 through G1 filled with text names (the same values as A2
through A7). In the matrix fields I calulate their correlations. In a
seperate field, say J1, I am calculating the highest correlation value from
my matrix. What I would like to do in cells K1 and/or L1 is find the
corresponding text names for that high correlation. So for example if cell
E1 is Red and cell A2 is Magenta and their correlation is .95, the highest in
the matrix, Cell J1 calculates .95. I would like cell(s) K1 and/or L1 to
return Red Magenta.

Hope this makes some sense - Happy New Year

Hi
try the following to array formulas (entered with cTRL+SHIFT+ENTER):
=INDEX(A1:G1,MAX(IF(B2:G7=J1,COLUMN(B2:G7))))
and
=INDEX(A1:A7,MAX(IF(B2:G7=J1,ROW(B2:G7))))
 
That works great, but my poor description was a little off ;-( More clearly
what I need to do is find a specific value from the matrix that may not be
the MAX value, and return the column & row - Thank you!
 
Don't let the MAX() in the formula fool you!

Manually enter *ANY* value in J1, and you'll see that you'll still get your
labels.
 
Yes, you are correct - I guess my problem is that I have duplicate values in
my sheet. Basically I have the same row headings & column settings - So,
when I have a Red/Magenta correlation, I also have a Magenta/Red Correlation
(same values in the cells). This seems to pose a problem with the formula.
 
Hi
yes it does. It returns the values for the max column/row in this case. What
would be your expected output for such cases?
 
As they would both be the same, it wouldn't matter to me, but currently it
seems to be unable to see either. Red/Magenta Magenta/Red, for me, means
the same thing. As long as if I am looking for their corresponding value,
say .95, that I receive one or the other.

Spreadsheet example:

Green Red Orange Magenta Blue
Green 1 .3 .25 .10 .7
Red .3 1 .6 .95 .21
Orange .25 .6 1 .8 .64
Magenta .1 .95 .8 1 .72
Blue .7 .21 .7 .72 1

So, basically if I put in a separate cell, say J1 the value .95, I would
like to receive Magenta Red as my return values. If I put .10 in cell J1,
I would like to receive Magenta Green. I am ignoring values = 1 , so those
duplications would not be included. And I am going out 5 or six decimal
places, so duplicates that are not the same column/row would not be an issue.

Thanks again.

Hi
try the following two array formulas in this case:
=INDEX(A1:F1,MAX(IF(B2:F6=J1,COLUMN(B2:F6))))
and
=INDEX(A1:A6,MATCH(J1,OFFSET(A1:A6,0,MAX(IF(B2:F6=J1,COLUMN(B2:F6)))-1),0))
 
SUPER-genius - Happy New Year!
Thank you!!!!
