( #3333=superdoc: print w/replies, xml ) Need Help??

I just ran that example through the code I posted (Note: My code uses letters for columns not rows as you have). The groupings produced:

23415 0000E 000BB 23415 AAAAA CCC0C DDD0D

gives rows 1 & 5 (your A & E), as a group which when subtracted from the remainer leaves rows 2, 3 & 4 (your {BCD}) as a group which is what you are after?

Full output from the unchanged program (except for inserting the new data (first line below)):

# my @grid = ( "AB0001","A0CD02","A0CD03","A0CD04","ABCDE5" ); c:\test>600418-2.pl This input AB0001 A0CD02 A0CD03 A0CD04 ABCDE5 sorted A0CD02 A0CD03 A0CD04 AB0001 ABCDE5 Tranformed looks like this AAAAA 000BB CCC0C DDD0D 0000E 23415 sorted 0000E 000BB 23415 AAAAA CCC0C DDD0D These are the sets where the letters denote the columns of the origina +l matrix (0 mean column not used in this set). And the numbers above, the rows they came from. 23415 0000E 000BB 23415 AAAAA CCC0C DDD0D

In the absence of evidence, opinion is indistinguishable from prejudice.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
