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'}

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)
