For n = 3:
starting_letter = 'D';
offset = xlscol(starting_letter);
n = 3+offset;
final_letter = xlscol(n);
range = strcat(starting_letter,num2str(1),':',final_letter,num2str(1));
Range:
'D1:G1'
For n= 16380
starting_letter = 'D';
offset = xlscol(starting_letter);
n = 16380+offset;
final_letter = xlscol(n);
range = strcat(starting_letter,num2str(1),':',final_letter,num2str(1));
Range:
'D1:XFD1'
In general, to find n, call the function with the name of the cell:
xlscol('XFD')
and subtract four to account for the offset.
