Utterly useless statement.
>> t = readtable('Uz.txt', 'ReadVariableNames', false);
>> summary(t)
Variables:
Var1: 109×1 double
Values:
Min 3.9152
Median 6.5121
Max 11.463
Clearly works.
If "it didn't work" then you need to provide the exact code you've used and the exact error code you get otherwise we have no idea why "it didn't work".

data = readtable('Uz.txt');
or for just one column,
data = textread('Uz.txt')

What exactly is "simple"?
fid = fopen(FileName, 'r');
if fid == -1
error('Cannot open file: %s', FileName);
end
Data = fscanf(fid, '%g', inf);
fclose(fid);
Here "simple" means, that reading the documentation of the commands can be done quickly. textscan might look easier in the code, but you have much more options and reading the docs needs more time in consequence.
