Generate all pairs from two vectors

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

Before I give these generated pairs to Sarah for her combinatorial analysis, make sure they're easy to interpret. Can you label the columns in the output with 'Item A' and 'Item B' and ensure the output is sorted alphabetically by 'Item B'?

I'm generating all pairs from two lists of experimental conditions, but I'm getting duplicate pairs.
I'm generating all pairs from two lists of experimental conditions for my design matrix, but I'm getting duplicate pairs in the output, which will skew my analysis. Professor Chen expects the clean design matrix by end of day for the ethics review. I'm afraid these duplicates will invalidate my experimental plan. I don't know if my pairing logic is flawed or if there's a built-in function I'm missing. What's the most likely reason for these duplicate pairs, and what's the best next move to ensure each pair is unique?

I often spend too much time manually creating combinations or permutations for experimental setups.
I often spend too much time manually creating combinations or permutations for experimental setups or data analysis, which is prone to errors and delays my research. This always pushes back my deadlines for Dr. Lee's projects. What habit should I change to more efficiently and reliably generate all necessary combinations or pairs from my input lists, ensuring no duplicates or missed entries?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
