I have a word that I switched to ASCII code. I then used a loop to make the resulting numbers change to the numbers that I want. My question is: how would I go about making those numbers appear as an array? They currently appear as:
ans=
ans=
ans=

" how would I go about making those numbers appear as an array? "
Most likely using indexing, as the introductory tutorials show:

I checked out the indexing tutorial, but all it talked about was finding certain numbers in an array that was already created.

Which is exactly the recommended approach:

It looks like your outputs are being produced within a loop. Instead of displaying their values within the loop, collect the values within a vector (or cell array if the values are not all numeric scalars) and then display the final result after the loop.
See this answer for a demo (but ignore the examples using eval()).

@Adam Danz: that is a curious page to link to: surely it would make more sense to link to a page explaining indexing (of which there are plenty in the documentation), rather than a page about avoiding dynamically naming variables (something the original question does not mention anywhere).

@Kyle Donk, the first two blocks of Jan's code in that answer (up voted 21x) demonstrate my suggestions. But also see Stephen's link to the Matlab documentation on preallocation.
