i want to transformate this function

function [pos vel Px] = DvKalman(z)

persistent A H Q R

persistent x P

persistent firstRun

if isempty(firstRun)

firstRun = 1;

dt = 1; % sec, for sonar

A = [ 1 dt ;

0 1 ];

H = [1 0];

Q = [ 1 0 ;

0 3 ];

R = 10;

x = [ 0 20 ]';

P = 5*eye(2);

end

% Kalman filter algorithm

xp = A*x;

Pp = A*P*A' + Q;

K = Pp*H'*inv(H*Pp*H' + R);

x = xp + K*(z - H*xp);

P = Pp - K*H*Pp;

pos = x(1);

vel = x(2);

Px = P ;

to a ssm Model

Are you talking about a Simulink model or a State Space Representation of the model in this function?

For a state space model see the documentation on ss and kalman:

doc ss

doc kalman
