Hello everyone. I have a simple question to ask since I am a bit confused. I have a following dummy code like this -

 iter = 1e2;
myvar= zeros(500,iter);
for k = 1:iter
    for ii=1:500
        %body of my code
        myvar(ii, k) = myvar(ii) + det (I_mat + var(ii) * A_mat);
    end
end

At the end of code, the variable "myvar" will store all the iterations data in the matrix of size 500x100. So my question is, how can i find the mean of each column of "myvar" matrix and plot this data? Any advice is really appreciated.

Thank you,
