Add the resulting array of each loop to a cell

I have some algorithm including a while loop:

 while  (condition)
    % do something and return a result array B
 end

Let's say:

 -Loop 1: B1=[1 2 3 4 5....9];
 -Loop 2: B2=[10 11 12....15]; 
 -Loop 3: B3=[16 17 18 19]   ;  
 -Loop 4: B4=[20 21 22....30];

How can I create a cell A={B1,B2,B3,B4} when the loop is finished?

For my real data, the while loop may be looping 100 times or more, the above is a simplification.

Solution

  • You can make use of the end keyword

    % Initialise empty cell array
A = {};
while *condition*
    % Create B using some calculation (different each loop)
    B = [1 2 3];
    % Other code ...
    % Assign to array
    A{end+1} = B;
end
