>> a=rand(4,1)
a =
0.67874
0.75774
0.74313
0.39223
>> b = randi(9,4,1)
b =
6
2
7
1
>> fprintf('the first number is %f and the second is %f\n',[a,b]')
the first number is 0.678735 and the second is 6.000000
the first number is 0.757740 and the second is 2.000000
the first number is 0.743132 and the second is 7.000000
the first number is 0.392227 and the second is 1.000000

You appear to have used %.lf (lower-case L) instead of %.1f (digit one)

Try this
fprintf('the first number is %0.1f and the second is %0.1f\n',a,b)
