How can I easily step through Matrix Combinations in Labview 7.1?

[Neville]

I have a 2D matrix of test parameters that I'd like to step through, hitting all possible combinations. I'd like the system to be dynamic so that I can input a matrix of any size.

The obvious solution is to use nested for loops, but I don't think that will allow me to handle dynamic matrix sizing. Any help would be appreciated! Thanks!

What do you mean by "hitting all possible combinations"? (e.g. All possible combinations of selecting k elements?).
Could you clarify your question? Thanks!

[Neville]

I mean that if you have a 3x3 matrix, you have 27 combinations and if you have a 3x4 matrix, you have 81 combinations. If I have an mxn matrix, I will have m^n combinations.

(Maybe this is obvious to everyboy except me, but ...)

Sorry for sounding a bit slow, but could you give a few examples for what you consider a "combination" from e.g. a 3x3 array?

I agree. I cannot find a combination or permuation way to manipulate the matrix to get the expected outcomes. An example will be exreemly helpful.

[Neville]

Sure. If I have a 3x3 matrix with the numbers 1,2,3 on the first row, 4,5,6 on the second, and 7,8,9 on the third, I want to generate the following matrix:
1,4,7;1,4,8;1,4,9;1,5,7;1,5,8;1,5,9;1,6,7;1,6,8;1,6,9;2,4,7;2,4,8;2,4,9;2,5,7;2,5,8;2,5,9;etc. I think you get the idea. : ) The trick here is this procedure has to be expandable to a matrix of any size. Thanks!

I have been on vacation. Here is a custom Braden algorithm. Enjoy!!
