MATLAB: Function xlsread too slow

importing excel dataspeedxlsreadxlswrite

Hey, I need to store data (values) in a file out of matlab, i.e. excel. The data needs to be imported when starting the matlab code and exported when closing. I've been using xlsread/xlswrite which is proofing pretty slow for that amount of data. Does anyone know a faster way?

you can use activeX servers.Example: http://www.mathworks.com/matlabcentral/answers/94822

You could use xlsfinfo() to get the sheet names and then you'll get the last sheet name.

[A, DESCR, FORMAT] = XLSFINFO('FILENAME')

Normally, 'DESCR' will return all the sheet names in a cell array.

MATLAB: How to rename a sheet in Excel using the COM interface in MATLAB

You can rename an Excel sheet using the "Name" property of a sheet object. For example the following renames the first sheet of an Excel file:

filename = 'C:\SomeExcelFile.xls';
% Open Excel Automation server
Excel = actxserver('Excel.Application');
% Make Excel visible
Excel.Visible=1;
% Open Excel file
Workbook = Excel.Workbooks.Open(filename);
% Get the list of sheets in the workbook
Sheets = Excel.ActiveWorkbook.Sheets;
% Rename the first sheet
Sheets.Item(1).Name = 'This is sheet 1';

The following code then saves the Workbook, quits Excel and removes the COM server:

% Save the file
Workbook.Save();
% Quit Excel, remove the COM server and delete the related objects
Excel.Quit();
Excel.delete();
clear Excel;
clear Workbook;
clear Sheets;
