hi , How do I activate the i (subscript) in Subscript[A, i] in order to display output in mm of array

 for r=1:(n-1)
    for i=1:mm
       if (out(i,1)<z(r)&z(r)<out(i,2))
           for j=1:mm
              if (out(j,1)<z(r+1)&z(r+1)<out(j,2))
                  Subscript[A, i](r)=Mid(j);
              end
           end
       end
    end
 end

mohammed - what is Subscript? What is A? Your notation

 Subscript[A, i](r)=..

using the square brackets is invalid so please describe what you are attempting to do here.

[mohammed elmenshawy]

i need the final output as mm of array ,, for exampel if (out(3,1)<z(4)&z(4)<out(3,2)) if (out(6,1)<z(5)&z(5)<out(6,2)) then the output is A3(4)=Mid(6) %such that 3 in last statment a result of loop . then in the code the output is A1,A2,..., Amm

[Geoff Hayes]

So...what is Subscript and what is A?

I would advise against using dynamically created variables which is what I think you are suggesting with your A1, A2, etc. This will just lead to errors. Better to use a cell array to collect all of this data.
