need a way to combine data of cells or strings with double matrix

colnames=get(handles.uitable,'Columnname');
colstring=cell(colnames);
%combineddata=???
filename=uiputfile('*.xlsx','Save File As');
xlswrite(filename,combineddata);

Best Answer

I think you mean
colstring = cellstr(colnames);
The column names would usually already be in cellstr format, but it doesn't hurt to specifically convert them just in case they were not. Likewise sometimes the Data from a uitable is a cell and sometimes it is an array, so
if ~iscell(doubledata)
  doubledata = num2cell(doubledata);
end
After that,
combineddata = [colstring; doubledata];
