Get the type of a variable

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.

The same task, four prompts

Tell me the data type of the variable 'sensorData' so I can confirm it's compatible with the next processing step.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed. Helpful?

Before I pass 'processedImage' to the segmentation algorithm, confirm its data type. I need to ensure it's a double-precision floating-point array, or the algorithm will throw an error and waste hours of computation time.

My calculation just failed with a 'type mismatch' error, and I'm unsure which variable is causing it.
My simulation just crashed with a 'type mismatch' error, and I'm afraid I've spent all afternoon debugging the wrong part of the code. I suspect it's either 'inputMatrix' or 'filterCoeffs', but I can't tell which one is the culprit without stopping the entire run. I don't know the best way to quickly inspect their types without breaking my current state. How can I diagnose the data types of these variables right now to pinpoint the mismatch and fix it?

I frequently encounter 'type mismatch' errors that force me to backtrack through my code, wasting valuable debugging time.
I constantly run into 'type mismatch' errors, especially when integrating new data or functions, and it always forces me to spend hours tracing back through the code. This costs me significant time on project deadlines. What habit could I change to proactively verify variable types, especially at critical interfaces, to prevent these frustrating and time-consuming errors?

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.
