Counting Match Pairs In Rows
 

I am trying to count the number of matched pairs by rows of data and
place this into a chart. Please see the screen shot example and manual
solution.

With the data sets:
1-2-3-4
1-3-4-5
2-3-4-6
3-4-5-6

I want to fill out the chart to find the number of times say 1&2 occur
in the same set and 1&3, 1&4, 2&3, 2&4, etc. The formula would be
filled into the result matrix.

Thanks for your help!

One way which delivers what you're after ..
(with result matrix extended to cover: 0,1,2,3 ... 9 on both axes)

Link to sample file:
http://www.savefile.com/files/6483947
File: Counting Match Pairs In Rows_bmb2000_wksht.xls

In Sheet1:

Data is in cols B to E, from row3 down

Put in S3:X3

S3: =B3&C3
T3: =B3&D3
U3: =B3&E3
V3: =C3&D3
W3: =C3&E3
X3: =D3&E3

Select S3:X3, copy down as many rows as there are sets of numbers

Put in Z1: '00 (include the leading apostrophe)
Put in AA1: =COUNTIF($S$3:$X$6,Z1)
Select Z1:AA1, copy down to AA100

In the matrix, we have the 2 axes
In H2:Q2 are the numbers: 0,1,2,... 9
In G3:G12 are the numbers: 0,1,2,... 9

Put in H3: =INDEX($AA:$AA,MATCH(H$2&$G3,$Z:$Z,0))
Copy across to Q3, fill down to Q12 to populate the grid

Now to colour the internals of the matrix using conditional formatting

Select H3:Q12
Click Format Conditional Formatting
Under condition 1, make it as:
Formula is: =ROWS($A$1:A1)<=COLUMNS($A$1:A1)
Format Patterns tab Black OK
Click OK at the main dialog

Oops, correction to formula in line:
Put in AA1: =COUNTIF($S$3:$X$6,Z1)

Put in AA1: =COUNTIF(S:X,Z1)

Thanks so much for your solution. I countinued to try and solve my
issue and came up with another method. Both seem to have their pros
and cons.

In my solution, I made another matrix that counts which numbers come up
in each data set. Then I did a sumproduct for each pair. See the
attached zip spreadsheet.

Thanks again!
