if i have a vector x=[0 6 7 7.....] and this x is measure with respect to a time vector then how can we find the derivative like dx/dt like the simulink block has the drivative, which computes with respect to simulation time but what can be done i case of MATLAB how this time vector can be differentiated with the x vector becasue both contain values. Any idea will be appreciated.

A simple brute force numerical derivative would be find the change in x and divide by the change in t;
dx = x(2:end) - x(1:end-1);
dt = t(2:end) - t(1:end-1);
v = dx./dt
