fileID1 = fopen('enct40.txt','wt');
fprintf(fileID1,'%s\n',cd1);
fclosef(fileID1);

but when I open the text file the leading and trailing zeros are disappear like this 'BA12CE' how can I print the results as they are without any missing values ?

Could you confirm that in the above that cd1 is '0BA12CE0' ? Already in character format?

This works here on R2016a,Win7

cd1 = '0BA12CE0';
fileID1 = fopen('enct40.txt','wt');
fprintf(fileID1,'%s\n',cd1);
fclose(fileID1);
type enct40.txt

output

0BA12CE0
