Estou tentando codificar o jogo da vida de Conway em Matlab, mas algo continua dando errado. Eu não recebo um erro, então eu realmente não sei o que estou fazendo de errado, simplesmente não faz nada. Eu acho que o problema pode ter algo a ver com a contagem das células (para verificar o número de vizinhos) ou incrementar as regras nas células na borda da matriz.

Aqui está meu código:

TIME = 10;
pulsar;     % creates begin matrix X
life{1} = X;
life = {};           % create list 'life'   

numrows = size(X,1); % calculate number of rows
numcolumns = size(X,2);  % calculate number of columns

current = X;        % make seed the first current(matrix you are starting off with in each step)
for i = 0:TIME;    % determine amount of times the loop will run
    nextnext = X;                     % create "nextnext" matrix to implement the rules of the game on (copy of X)
    for row = 2:numrows-1;              % for each row
        for column = 2:numcolumns-1;    % for each column
            east_of_row = column + 1;      % define how to count the cell right of target cell
            west_of_row = column - 1;      % define how to count the cell left of target cell             
            north_of_column = row - 1;     % define how to count the cell north of target cell              
            south_of_column = row + 1;     % define how to count the cell south of target cell               

            % count neighboring cells:
            neighbors = 0;                               % start counter 'neighbors' with 0

            while east_of_row <= size(X),
                 west_of_row <= size(X);,
                 north_of_column <= size(X);,
                 south_of_column <= size(X); 
                 if current(row,east_of_row) == 1              % if neighboring cell has a value of 1
                     neighbors + 1;                                 % add 1 to neighbors
                 end
                 if current(row,west_of_row) == 1              % if neighboring cell has a value of 1
                     neighbors + 1;                                  % add 1 to neighbors
                 end
                 if current(north_of_column,column) == 1       % if neighboring cell has a value of 1
