How can I assign numbers to variables names?

Hi all,

How can I assign numbers to variables names without making them vector elements, for example how we write the following for loop: for i=1:5 Ai=i^2; end in such a way that the result is: A1=1 A2=4 . . A5=25

That's a very bad idea and there are already several similar questions at matlab answers.

How do I make a series of variables A1, A2, A3, ... A10?

than you very much for answering

@Salah: accept Paulo's answer if you think he answered your question.

Why does this question keep coming up, I wonder...?

[Walter Roberson]

The Endless September perhaps...

[Matt Tearle]

Ouch. But seriously, why the sudden glut of virtually identical queries about a ill-advised practice? I've noticed some clumping of topics so far -- passing parameters to function functions, surface plots of vector data, now variables with numeric names. Weird.

It is almost like we need a FAQ or something...

[Matt Fig]

I bet if we had just two hyper-linked lines show up somewhere in the process of posting a question, something like:

Are you wondering how to make variables like A1, A2, A3, A4, etc?

Are you wondering why == cannot find your number in an array?

That we could reduce these types of posts significantly. I don't think these two most common FAQs would make the Question submission process that much more cumbersome.

@Matt: Please send this to Helen ([e-mail]). Or better: Let the user confirm, that the question cannot be solved by reading these two links.

arrayfun(@(x) ['A',num2str(x)],[1:10],'uniformoutput',false)

[Oleg Komarov]

Which doesn't accomplishes what the OP asked.
