Q= sqrt(N(i)*3);
This is the code that I have written.I want the existing arrays to be made into a table where I can add column name.And the values should be converted in integers.

Here's how to put your variables into a table with column names.
table(N',Q',CI',CIinDB', 'VariableNames', {'N' 'Q' 'CI' 'CIinDB'})
"Convert them to integers" - use round() for each variable above or use your 't' variable as shown below.
array2table(round(t), 'VariableNames', {'N' 'Q' 'CI' 'CIinDB'})

I don't understand the difficulty you're facing. What's wrong with just using table to create the table directly from your variables, or array2table if you really want to go through the matrix?
N = N'; Q = Q'; Cl = Cl'; ClinDB = ClinDB'; %of course if you created N as a column vector you would not need to transpose anything
yourtable = table(N, Q, Cl, ClinDB);
yourtable = array2table(t, 'VariableNames', {'N', 'Q', 'Cl', 'ClinDB'});
It's all very well documented.
Note that, in
%N = a_vector_with_10_elements;
i = (1:10) %parentheses completely redundant. It's the same as i = 1:10
Q = sqrt(N(i)*3)
the little trip through i is a complete waste of time.
Q = sqrt(N)*3)
does exactly the same.
