Thread Subject: problem with xlswrite1

i tried to use xlswrite1 instead of xlswrite and, as i call it from some functions of mine and not from the command line, i changed, as suggested, the first line in

Excel = evalin('caller', 'Excel');

but it gives me the following error:

??? Undefined function or variable 'Excel'.

how can i fix it? :)

thanks

Are you sure you have Excel installed?
If so, here is the code I use to startup excel, use xlswrite1(), and
shutdown Excel:

%----- Open Excel for writing.
Excel = actxserver('Excel.Application');
if ~exist(excelFileName, 'file')
ExcelWorkbook = Excel.workbooks.Add;
ExcelWorkbook.SaveAs(excelFileName, 1);
ExcelWorkbook.Close(false);
end
Excel.Visible = true; % Make Excel visible.
% Open up workbook.
invoke(Excel.Workbooks, 'Open', excelFileName);
% Save the reference to this workbook so that we can later activate
it, in case we open multiple workbooks.
%wbNumber1 = Excel.ActiveWorkbook;

% Do the actual writing of the data to the open worksheet.
xlswrite1(excelFileName, dataArray, 'MySheetname', 'C3');

invoke(Excel.ActiveWorkbook,'Save'); % Save to disk.

% Shut down Excel.
Excel.Quit
Excel.delete
clear Excel; % Remove variable from workspace.
Good luck,
