how do i make the syntax for looping to have an output of A1, A2, A3, A4... A(n)? cant use A(n) since matlab will read it as an array.

You can use A(n) if your data are numbers or char (same class),

example:

 A=[10 20 30 40 ]; 
 A(1)
 A(2)
 ...

use A{n} if your data are both, or same class with different sizes

A={'color','price';'red','100';'green','200'}

i need to show A1, A2, A3 to An. which will have its values

sample output:

A1---------3---------5---------6

A2---------5---------3---------4

A3---------6---------7---------9

(sorry for using -, spaces dont work)

If it is just output and not variable names, then

fprintf('A%d', n)

A=[3 5 6;5 3 4;6 7 9] %example
out=[];
for k=1:size(A,1);
out=char(out,[sprintf('A%d  ',k) num2str(A(k,:))]);
end
disp(out)
