How to call a matlab function?

I have to verify that my matrix code is correct by checking that for a 5x5 matrix, SS=I_5. How do I do that? This is the code I have for returning a matrix S of any size.

function S = S_Matrix(m)
    S=zeros(m)
    for ii= lim ;
        for jj= lim ;
            S(ii,jj)= sqrt(2/m)*sin*((pi/m)*(ii-(1/2))*(jj-(1/2)));
        end
    end
 
end

Where is the function definition of lim?

Did you follow a basic Matlab tutorial?

The above code cannot be executed as lim is not defined. Try initializing lim either as a variable or function with integer return value.
