在Matlab中使用Excel中的date
我正在创build一个实用程序，它会给用户一个提示，并要求他们的crn＃，section＃和老师的姓。 一旦进入，用户将收到他们的考试时间，date和地点。 我有一个与我的Excel电子表格和使用Mac OS的问题。 尽pipedate显示为（。）而不是类似于（01/01/0001）
这里是代码
这里是电子表格，使代码工作; https://www.dropbox.com/s/drwmk1dinbfwfvl/DrexelFinalsWinter13.xlsx?m
close all; %% I created an Excel file to hold the information located on Drexel's %% website witch contains exam times and locations based on certain criteria %% First I have to make code to read the excel file created clc [ndata, text, alldata]=xlsread('DrexelFinalsWinter13.xlsx'); %% Next we will prompt the user for specific data by creating a dialog box %% using the prompt command. clc prompt={'Your CRN #','Your Section #',... ' Your Instructors Name' }; numlines=1; defaultanswer={'22081','001','Hawkins'}; name='Enter Info'; options.Resize='on'; options.WindowStyle='normal'; options.Interpreter='tex'; answer=inputdlg(prompt,name,numlines,defaultanswer); %prompt user for data a1=cell2mat(answer(1));c1=str2double(a1); %converting cell info to numeric a2=cell2mat(answer(2));c2=str2double(a2); %converting cell info to numeric w=0; for p=1:1032; if (isequal(c1,cell2mat(alldata(p,1))) && ... (or(isequal(c2,cell2mat(alldata(p,4))),... isequal(answer(2),alldata(p,4)))) && ... isequal(answer(3),alldata(p,6))); % the if condition looks to see if % our input matches any data in the table % we cant use cell data below for comoarison so I had to % convert it to matlab common data like num or double % for numbers because the xlsread function cant % distinguish them and only know strings w = w+1; date = cell2mat(alldata(p,7)); time = cell2mat(alldata(p,8)); loca = cell2mat(alldata(p,9)); fprintf('Your exam date is %s. \n',date); % print date results fprintf('Your exam time is %s. \n',time); % print time results fprintf('Your exam location is %s. \n',loca); % print location results disp('Good luck with your exams! Sleep well & eat a healthy breakfast!'); % just for kicks elseif p==1032 && w==0 %if we didnt find any matches from our prompt 'You have provided wrong data or no exam is scheduled for your class.'; end end % The outputs are then located in the command line like below % answer to the defult values % Your exam date is 3/19/2013. % Your exam time is 0800-1000. % Your exam location is See Department. % Good luck with your exams! Sleep well & eat a healthy breakfast! 尝试这个：
fprintf('Your exam date is %s. \n',datestr(x2mdate(date))); % print date results
看看x2mdate文档，如果你有财务工具箱，否则你可以这样做：
fprintf('Your exam date is %s. \n',datestr(date + datenum('30DEC1899')));
