for loop for variables

I have written one code as follows,

for i=1:10
  Ai=i;
  fprintf('A is: %d \n',Ai)
end

what i want to achieve from here is, I want to store 1,2,3..10 in variables A1,A2,A3...A10. But the code i have created is giving me Ai as variable instead A1,A2...etc and storing Ai=10 at the end.(It has also created row vector A=[1:10])

It's not a good idea to create variables A1,A2, ..., An. The array A=1:10 contains all your data. Why to create 10 variables, when one variable is sufficient

Actually sir I wanted to do the operations on each of them separately that's why i want to store them at different variables.

@Stephen: Haha I read the same thing somewhere online. But that didn't stop me :3

for i=1:10

    eval(sprintf('A%i = i',i))

end

Thank you sir. I will try this code on images and will let you know. Thank you very much

@Scott: this is how it often goes:

• beginner: I have a great idea!
• experienced user: what?
• b. I will access my variables dynamically!
• e. Don't do that, it is inefficient, complex, buggy, and hard to debug. Here is why...
• b. No! I am really cunning, and I know more than every experienced user who is advising me to use better, more reliable methods! I even know better than TMW, who wrote a whole page about avoiding dynamic variable names.
• e. Here are some better ways to...
• b. I am so great, it works!!!
• e. sigh.

Three years later:

• slightly-more-experienced beginner: damn, I have to rewrite all of this awful, slow, buggy code that I wrote! And I have to unlearn all these bad habits!

It been three years, and yeah that did happen. Can't even understand what I code.
