xlswrite_mod

Modified version of xlswrite_mod. I needed to write to more than 702 columns (ZZ) since with Excel 07 it can support up to 16000 columns (XFD). I added a third character so from ZZ it will become AAA, AAB...AAZ, ABA,ABB,ABC,...ABZ and so forth. Tested upto 2500 columns using a simple matrix and it works. I have not tried using column offset such as when you defined which column to start writing. Feel free to modify/comment and correct it if there is any mistake.

Some simple test:
% test array, create 25x2500, test for
% excel write
for i = 1:25
for j = 1:2500
testArray(i,j) = j;
end
end
filename = 'testArray.xlsx';
xlswrite_mod(testArray(1:25,1:2054),{},{},filename);
% End of testArray
