% Open Excel, add workbook, change active worksheet,

% get/put array, save, and close

% First open an Excel Server

Excel = actxserver('Excel.Application');

set(Excel, 'Visible', 1);

% Insert a new workbook

Workbooks = Excel.Workbooks;

Workbook = invoke(Workbooks, 'Add');

% Make the second sheet active

Sheets = Excel.ActiveWorkBook.Sheets;

sheet2 = get(Sheets, 'Item', 2);

invoke(sheet2, 'Activate');

% Get a handle to the active sheet

Activesheet = Excel.Activesheet;

% Put a MATLAB array into Excel

A = [1 2; 3 4];

ActivesheetRange = get(Activesheet,'Range','A1:B2');

set(ActivesheetRange, 'Value', A);

% Get back a range. It will be a cell array,

% since the cell range can

% contain different types of data.

Range = get(Activesheet, 'Range', 'A1:B2');

B = Range.value;

% Convert to a double matrix. The cell array must contain only scalars.

B = reshape([B{:}], size(B));

% Now save the workbook

invoke(Workbook, 'SaveAs', 'myfile.xls');

% To avoid saving the workbook and being prompted to do so,

% uncomment the following code.

% Workbook.Saved = 1;

% invoke(Workbook, 'Close');

% Quit Excel

invoke(Excel, 'Quit');

% End process

delete(Excel);
