Define an array with variable

Hello, I wonder how can I define an array with a variable, for example,

x_i=an array, where i changes. I do not think Matlab allows such operations. How can I accommodate it? Later on I will use x_i in loops.

Thanks.

No worries! That's what we're here for :)

And, as a forum, if we prevent just a few people from creating A1, A2,... An, then we've been successful!

Thanks, Sean. Are you working at Mathworks? I use Matlab heavily on computing and I wish I can have opportunity to improve the speed of MATLAB.

k=4 
assignin('base',sprintf('x_%d',k),[1 2 3])
