Codegen Errors. How to do It

I have one function which is quite slow in bigger Data, I m interested to convert into C (Mex). I tried one example.

my function in .m is

function mm=myMatching(F1,F2)

[numN, tf1] = size(F1); % total features in img1 and neighbors
tf2 = size(F2,2); % total features in img2

mm = zeros(tf2, tf1);
for i=1:tf1
    for j=1:tf2
       m = sum(ismember(F1(:,i), F2(:,j))); 
       mm(j,i) = m/numN; 
    end    
end

When I execute following code

codegen myMatching.m -args {t1,t2}
where t1 and t2 are sample matrix

when I execute

t= myMatching_mex(t1, t2);

then it works fine. However, if the dimensions of t1, or t2 are changes then it gives error. How can I make it general.

You should be using coder.varsize()
