function [FHQRinitx initV] = AR_to_SS(coef C y)
%
% Convert a vector auto-regressive model of order k to state-space form.
% [FHQR] = AR_to_SS(coef C y)
%
% X(i) = A(1) X(i-1) + ... + A(k) X(i-k+1) + v where v ~ N(0 C)
% and A(i) = coef(::i) is the weight matrix for i steps ago.
% We initialize the state vector with [y(:k)‘ ... y(:1)‘]‘ since
% the state vector stores [X(i) ... X(i-k+1)]‘ in order.
[s s2 k] = size(coef); % s is the size of the state vector
bs = s * ones(1k); % size of each block
F = zeros(s*k);
for i=1:k
F(block(1bs) block(ibs)) = coef(::i);
end
for i=1:k-1
F(block(i+1bs) block(ibs)) = eye(s);
end
H = zeros(1*s k*s);
% we get to see the most recent component of the state vector
H(block(1bs) block(1bs)) = eye(s);
%for i=1:k
% H(block(1bs) block(ibs)) = eye(s);
%end
Q = zeros(k*s);
Q(block(1bs) block(1bs)) = C;
R = zeros(s);
initx = zeros(k*s 1);
for i=1:k
initx(block(ibs)) = y(: k-i+1); % concatenate the first k observation vectors
end
initV = zeros(k*s); % no uncertainty about the state (since perfectly observable)
