algorithm to select each elements (number)

1)I want an algorithm which will have this table A=[1 2 3 4 5]

2) to select each elements (number) for each line only once and when it goes to the next have the opportunity to once again select the same number with a different

3) each time selected three elements will calculate all the combinations that can make and my displays them every time and what their combinations

4) I would like to run the algorithm before the upload will I wanted to be written for older versions of matlab

Each , after go to the next line

B.C
1  3 4,
2  4 5,
3  5 1,
2 3 4,
1 4 5,
2 5 3,
1 5 4,
,,,,,,
,,,,,,,

combinations are above other I put some

You may want to clarify some of your steps. What do you mean ...have the opportunity to once again select the same number with a different? Different what?

Please provide a small example with output from each step of your algorithm.

Each , after go to the next line

B.C 
1 3 4, 
2 4 5,
3 5 1,
2 3 4, 
1 4 5, 
2 5 3, 
1 5 4, ,,,,,, ,,,,,,,

is 7 combinations , are above other I put some

Your question is very unclear. Most of your sentences are hard to understand, I'm afraid.

From your example, it would appear you want:

B = nchoosek(A, 3)

Show me similar command if it is unique then I do if there are similar command would like to wish to write the

I don't understand either (that makes 3 of us). Perhaps you can get another English speaker to review your question, then edit it to update it with a better explanation.
