Create Named Ranges in Excel using Matlab

This MATLAB code solved the issue. It took some digging and experimentation so I figured I would share it:

function NameRange(r2,c2,b2,RangeName,SummaryFileName,SheetName)
% --------------------
% Function: NameRange
% Description:
% This script names a specific range in Excel
%
% input: 
% r2 = rows in data being written to Excel i.e. size(matrix, 2)
% c2 = columns in data being written to Excel i.e. size(matrix,1)
% b2 = the starting cell you are writing to i.e. whatever cell you put into xlswrite i.e. 'A2'
% Rangename = What you want to name the range
% SummaryFileName is the address to the file, '**FILENAME**.xls'
% Sheet Name is the worksheet name i.e. 'Doc Details'
%
% Example: NameRange(5,6,'A3','Tester1234','**FILENAME**.xls','Doc Details')
%
% Output - named range
% If you named a sheet incorrectly, this is one of the Possible Errors
% Description: The name that you entered is not valid.
% 
% Reasons for this can include:
%   -The name does not begin with a letter or an underscore
%   -The name contains a space or other invalid characters
%   -The name conflicts with an Excel built-in name or the
%     name of another object in the workbook

% ----------------------

% Create object.
ExcelApp = actxserver('Excel.Application');
% Show window (optional).
ExcelApp.Visible = 1;
% Open file located in the current folder.
ExcelApp.Workbooks.Open(SummaryFileName);
% create handle for parsing sheets
Sheets = ExcelApp.ActiveWorkBook.Sheets; 
% grab the specified sheet
cursheet = get(Sheets, 'Item', SheetName);
% calculate start and end
[cr1, cr2]=nn2an2(r2,c2,b2);
A1Notation = [cr1 ':' cr2];
cursheet.Range(A1Notation).Name = RangeName;

% Pull the shortname from the path to close the file
[pathstr, name, ext] = fileparts(SummaryFileName);
ShortName = [name ext];

 Excel = actxGetRunningServer('Excel.Application');
 Excel.WorkBooks.Item(ShortName).Save;
 Excel.WorkBooks.Item(ShortName).Close;
 Excel.Quit;

function [cr1 ,cr2] = nn2an2(r2, c2, b2)
% r1 and c1 is the size of the data you are writing to matlab, and b2 is
% the starting cell

% convert alpha, number format to number, number format
% this is the starting cell 
t = find(isletter(b2));
t2 = abs(upper(b2(t))) - 64;
if(length(t2) == 2), t2(1) = t2(1) * 26; end
c1 = sum(t2); r1 = str2num(b2(max(t) + 1:length(b2)));

% find the other corner of the matrix in A1 notation by adding the two
% together
c3 = c1+c2-1; 
r3 = r1+r2-1;

% convert number, number format to alpha, number format
t3 = [floor((c3 - 1)/26) + 64 rem(c3 - 1, 26) + 65];
if(t3(1)<65), t3(1) = []; end
% other corner found
cr2 = [char(t3) num2str(r3)];
cr1 = b2;
end

end
