How do I write data to an Excel Spreadsheet with a custom cell background color and custom font color via MATLAB?

I have data that I want to write to a cell in an Excel Spreadsheet, but I also want to assign a background color and font color to this cell. I would like to know the way to do this through MATLAB.

This task can be accomplished using ActiveX with Excel. The following example function shows one way to do this:

function xlscolor(file, data, range)
    %XLSCOLOR writes data like XLSWRITE 
    %but adds color options
    %  XLSCOLOR(FILE,DATA,RANGE) writes the variable in
    %  DATA to FILE, in the range specified by RANGE.  
 
    %Obtain the full path name of the file
    file = fullfile(pwd, file);

    %Open an ActiveX connection to Excel
    h = actxserver('excel.application');

    %Create a new work book (excel file)
    wb=h.WorkBooks.Add();
 
    %Select the appropriate range
    ran = h.Activesheet.get('Range',range); 

    %write the data to the range
    ran.value = data; 
 
    %The color is specified as an BGR triplet in hexadecimal notation
    %RED = 0000FF
    %BLUE= FF00FF
    %GREEN=00FF00
    %BLACK=000000
    %WHITE=FFFFFF
    ran.interior.Color=hex2dec('00FF00'); %Green
    ran.font.Color=hex2dec('FF0000');     %Blue
 
 
    % save the file with the given file name, close Excel
    wb.SaveAs(file); 
    wb.Close;
    h.Quit;
    h.delete;
end

Example invocation:

    xlscolor('Tone.xls',rand(5,5),'A1:E5')
