如何在inputdlg中將字符串輸入爲字符串？

Question

（R2016b：Matlab的版） 我想在inputdlg作爲字符串的用戶輸入，然後將所有的輸入串的陣列的單元爲一個可變

我的代碼是：

prompt = {'Input the number of Criterion','Input short name of criterion'}; 
    dlg_title = 'Alternative Evauation'; 
    num_lines = 1; 
    defaultans = {'3','{Criterion1,Criterion2,Criterion3}'}; 
    answer = inputdlg(prompt,dlg_title,num_lines,defaultans);  

儘管我我能讀number of Criterion作爲

n=str2num(answer{1}) 

但是當我嘗試讀取short name of criteria作爲

str=answer{2} 

然後而不是讀取str作爲陣列 'Criterion1', 'Criterion2', 'Criterion3'單獨的細胞，它讀取Criterion1Criterion2Criterion3 我想可變str作爲

str={'Criterion1', 'Criterion2', 'Criterion3'...} 

上有輸入number of criterion沒有限制，它可以是5或7取決於用戶，所以相應name of criterion會增加

事情是inputdlg返回一個單個字符串爲每個輸入變量。您可以使用strsplit這個字符串分割成幾個標準名稱：

prompt = {'Input the number of Criterion','Input short name of criterion'}; 
dlg_title = 'Alternative Evauation'; 
num_lines = 1; 
defaultans = {'3','Criterion1,Criterion2,Criterion3'}; 
answer = inputdlg(prompt,dlg_title,num_lines,defaultans); 
% get number of criterions 
n = str2num(answer{1}); 
% get criterion default names (cell array of size [1 n]) 
defStr = cellfun(@(name,num) [name num2str(num)],... 
    repmat({'Criterion'},[1 n]),num2cell(1:n),'UniformOutput',0); 
% get user supplied criterion names and split by commas 
temp = strsplit(answer{2},','); 
str = defStr; 
% assign user's names instead of default ones 
str(1:numel(temp)) = temp;
