angular distribution of power spectrum
Hi, I've been trying to compute the angular average of the power spectrum i.e. finding how much power is concentrated at different orientations/angles. The code I have is as follows: function angswath3(pwrspec) %pwrspec is the power spectrum clc; [N N] = size(pwrspec); % coordinates of the power spectrum [X ... 3 May 2010 13:08

summation for specific indices
Hello, I'm trying to do the following summation without a for loop: I have one array which looks smthg like: f=[1 1 1 ; 1 1 3 ; 1 4 4 ; 2 1 1 ; 2 1 4 ; 2 4 4 ] And another array: A=rand(size(f,1),1); And I want to add all rows of A such that the last two values in the correspondi... 3 May 2010 03:21

Incorporate both measurement noise and system disturbance in idmodel object.
Hello, I have estimated a disturbance model as well as a noise model acting on my output. I have a model of the type x´=A*x+B*u+K*v1 y = C*x+D*u+v2 where v1 = [w; v2] - a vector with white noise. Now I want to convert this to discrete time... and I'm trying to utilize the idmodel functionality. I have only one ... 4 May 2010 19:04
