Hello. I am facing some problem with Matlab coding. I want:

   if working_mode == 1
          a = func_con(x);
          save a;
    else           %%%Here, i want to use the value of "a"
           a;   
           for i = 1:3
                 if a > 10
                       a = func_rep(a);
                 else break,
                 end
                 a;
           end
      end

How can i perform this operation? Any help will be appreciated. Thanks.

Hi,

if a doesnt exist than you cant use it. But you can use ifempty to check if the variable a is filled with data, e.g.

   a = [];
   if working_mode == 1
          a = func_con(x);
          save a;
    else   %%%Here, i want to use the value of "a"
        if ~isempty(a)
           a;   
           for i = 1:3
                 if a > 10
                       a = func_rep(a);
                 else break,
                 end
                 a;
           end
        else
           disp('a doesnt contain data')
        end
      end
