How to extract Signal Parameters from an Eye Diagram

Hello and Good day every one

I have this eye Diagram which I attached its code the data to run the code and plot the eye. I have this eye diagram:

Now I want to extract some vital information about the signal such as Cross over area in eye diagram (jitter), signal to noise ratio (Distortion), Bit error rate, Slope of the eye (Sensitivity), Eye height, width and amplitude and pretty much everything possible about the signal one can read from an eye diagram. I do not know how to manipulate my data to achieve these parameters.

The code:

load('eye2.mat')

hold on;

for k = 1:N_symb

u_idx = samp_per_symb*(k - 1) + rel_idx;

if (k == 1) || (k == N_symb)

u_idx = mod(u_idx - 1, N_samp) + 1;

end

plot(t_plot, real(u(:, u_idx)),'k');

end

ylabel('I channel')

grid on;

zoom on;

box on;
