Best Answer

Yes, you can.

Range=get(handleEdit,'string');
set(handleSlider,'Max',str2num(Range));

MATLAB: Dynamic ranges using xlswrite

You can do this by dynamically creating the character string that you send to xlswrite to specify xl range.

Something like this:

>> firstRow = 1;
>> lastRow = 5;
>> firstCol = 'C';
>> lastCol = 'AY';
>> cellRange = [firstCol,num2str(firstRow),':',lastCol,num2str(lastRow)]
cellRange =
C1:AY5

The only thing left, is to figure out what "lastCol" is based on the column number. I wrote a function to do this myself a little while back. I know there are other versions floating around as well.

For example:

>> xlcolumnletter(51)
ans =
AY

Here's the code:

function colLetter = xlcolumnletter(colNumber)
% Excel formats columns using letters.
% This function returns the letter combination that corresponds to a given
% column number.
% Limited to 702 columns
if( colNumber > 26*27 )
    error('XLCOLUMNLETTER: Requested column number is larger than 702. Need to revise method to work with 3 character columns');
else
    % Start with A-Z letters
    atoz        = char(65:90)';
      % Single character columns are first
      singleChar  = cellstr(atoz);
      % Calculate double character columns
      n           = (1:26)';
      indx        = allcomb(n,n);
      doubleChar  = cellstr(atoz(indx));
      % Concatenate
      xlLetters   = [singleChar;doubleChar];
      % Return requested column
      colLetter   = xlLetters{colNumber};
  end
