Possible index combinations in 2D array - more Math Question than LabView???

[Mim]

Hi All,

I accidently submitted the first post.. please disregard the previous one.

I am struggling with this problem. Please HELP!!!

I have an array of numbers:

Set1  50     62    73    82       91     96   100
Set2  43     78    146  186     230   255
Set3  0.25  2      6     12       20
Set4  5       50    500   2000  8000
Set5  5       50    500   2000  8000

I need to create all possible combinations for Set1 through Set5.

Example:

{50, 43, 0.25, 5, 5}

{50, 43, 0.25, 5, 50}

{50, 43, 0.25, 5, 500}

{50, 43, 0.25, 5, 2000}

{50, 43, 0.25, 5, 8000}

{50, 43, 0.25, 5, 5}

{50, 43, 0.25, 50, 5}

{50, 43, 0.25, 500, 5}

{50, 43, 0.25, 2000, 5}

{50, 43, 0.25, 8000, 5}

{50, 43, 0.25, 5, 5}

{50, 43, 2, 5, 5}

{50, 43, 6, 5, 5}

{50, 43, 12, 5, 5}

{50, 43, 20, 5, 5}

and so on....

I just can't figure out how to loop this through to go through all possible combinations of the 5 sets. :((

Looking forward to your suggestions and help.

Thanks,

Mim

You have to have 5 nested loops.
Let's call your COLUMNS A-E and your ROWS 0-4:

A0 B0 C0 D0 E0
A1 B1 C1 D1 E1
A2 B2 C2 D2 E2
A3 B3 C3 D3 E3
A4 B4 C4 D4 E5

Extract all the COLUMNS.

Take COLUMN A and autoindex it on the first (outside) loop:
  For i = 0 to 4
    Ax = A[i]
Pass Column B THROUGH the first FOR loop and autoindex it on the second loop:
    For i = 0 to 4
      Bx = B[i]  // autoindexing will do this for you
Pass Column C THROUGH the first and second FOR loop and autoindex it on the third loop:
      For i = 0 to 4
        Cx = C[i]  // autoindexing will do this for you
and so on:
        For i = 0 to 4
          Dx = D[i]  // autoindexing will do this for you
          For i = 0 to 4
            Ex = E[i]  // autoindexing will do this for you
Assemble Ax, Bx, Cx, Dx and Ex into a set and do with it what you want.

Just do five nested loops and remember to autoindex A on the outside loop, B on the 2nd, C on the 3rd, D on the 4th, and E on the inside loop.

I think you will get 5^5 combinations.
