Differentiated estimation of independence of components of a casual vector

基于极坐标的牛顿拉夫逊潮流计算，MATLAB编程，只要把里面地址改成自己的地址就可以用了(Based on polar coordinates Newton Raphson power flow calculation, MATLAB programming, as long as the inside address into the address can be used)

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.
