how to make new variables and values in for loop

I want to make and define variables with for loop like:

for i=1:3

something

Ai = ...

something

end

so that after running this, I have defined variables of Ai, or A1, A2, A3 in this case

I tried to search and found out there is something such as A{i} or saving values to arrays, but in the end I need to transform them again as the above and get separate defined variables...

Thank you.

"I have defined variables of Ai, or A1, A2, A3 in this case"

Do NOT do this. The MATLAB documentation specifically recommends against dynamically accessing variable names, as do all experienced MATLAB users. Read this to know why:

"I tried to search and found out there is something such as A{i} or saving values to arrays,"

This is exactly what you should do. Indexing is simple, neat, easy to debug, and very efficient (unlike what you are trying to do).

":..but in the end I need to transform them again as the above and get separate defined variables..."

I very much doubt that you "need" to do that. Please explain your usecase in more detail.

Adding to Stephen‘s comment , also learn to preallocate!

Please do not create numbered variables!

If you want varying values for different iterations, subscript ‘A’ instead:

A(i) = ...

or:

A{i} = ...

depending upon what you want to do, and the size of ‘A’.
