%% Step 1: 读入数据

phasedata = readtable('phasedata.txt');

%% Step 2: 提取数据

time = phasedata(:,1);  % 提取地址

time= table2cell(time); % 转换数据类型

phase = phasedata(:, 8);  % 提取相位

phase = table2cell(phase);

%% Step 3: 预处理数据

len = length(time); % 返回数据长度

matchData = regexp(time, '^\[.*]', 'split'); % 裁剪数据

%% Step 4：提取处理过后的数据

idStr = cell(len, 1);

for i=1:len

    idStr{i} = matchData{i}{2};

end

phase = regexprep(phase, 'A', '1');

phase = regexprep(phase, 'B', '2');

phase = regexprep(phase, 'C', '3');

%% Step 5: 输出数据

id = cell2table(idStr);

phase = cell2table(phase);

newTable = [id, phase];

writetable(newTable,'myData.txt','Delimiter',' ','WriteVariableNames', false);
