问题描述

我想在 MATLAB 中打开和关闭一个 Excel 文件.我已经尝试过 下面的代码，但它在使用

I want to open and close an Excel file in MATLAB.I have tried the code below, but it failed on closing process with actxserver

h.WorkBooks.Item(wbkname).Close;

这是我解决此问题的代码，如何终止 excel 文件?

here is my code for this issue, how can I terminate the excel file?

.Quit
.delete

我也尝试通过 VBA 子模块关闭 excel 文件，但它给了我一个错误消息:

I also tried to close excel file via VBA sub-module, but it gives me an error message:

fullFileName  = [pwd 'KOSPI200_1월.xlsm'];
excel = actxserver('Excel.Application');
file = excel.Workbooks.Open(fullFileName);
excel.Run('jongho_bot_initial');
excel.Run('jongho_bot_loop',2);

推荐答案

这是一个创建新电子表格、写入一些值、保存文件并退出的示例.Excel 进程最终完全终止.

Here is an example that creates a new spreadsheet, write some values, save the file and exit. The Excel process is cleanly terminated at the end.

% create Excel COM server
excel = actxserver('Excel.Application');
excel.Visible = true;  % make the window visible

% create new workbook
wb = excel.Workbooks.Add();

% get "Sheet1" and activate it
sheet = wb.Sheets.Item(1);
sheet.Activate();

% select a 5x5 range, and fill it with some numeric values
sheet.Range('A1:E5').Value = num2cell(magic(5));

% save spreadsheet file
excel.DisplayAlerts = false;  % overwrite file without prompts
wb.SaveAs(fullfile(pwd(),'myfile.xlsx'));

% close spreadsheet
wb.Close(false);

% quit Excel
excel.Quit();

% delete handles and clear variables
delete(excel);
clear sheet wb excel

如果您希望在后台执行自动化操作而无需用户交互:

You might additionally want to set certain properties appropriately, if you want the automation to be performed in the background with no user interaction:

excel.Visible = false;         % invisible Excel window
excel.ScreenUpdating = false;  % turn off screen update to run faster
excel.Interactive = false;     % non-interactive mode, with no keyboard/mouse
excel.DisplayAlerts = false;   % no prompts or alert messages
excel.UserControl = false;     % object freed when reference count reaches zero
