formating strings

str = 'The range for int8 is:\n\t %d to %d ';
 % the \t used the print something like :
 %             output
 % instead of:
 % output
 
 
sprintf(str, intmin('int8'), intmax('int8'));
 % Whave we have done here is : printing a string then  go to the next line (\n) then add some tabs (\t) then print the two nubers (%d a_string %d)
 
 
 
 
 % here are two ways creat a 2 dim  array with strings
