MATLAB: Dimensions of matrices being concatenated are not consistent.

concatenatedMATLAB

Hi, im having trouble in running a programm for the following reason: Dimensions of matrices being concatenated are not consistent.
vector names correspond to the forecast error decomposition of variance, as mentioned in %P=chol(Omega); Choleski factorization
However vectors have the same number of columns:
Y=data;
% will print results to the MATLAB command window
% set flag for Sim's correction factor
sims = 1;
maxlag = 12;
minlag = 1;
lrratio(Y,maxlag,minlag,sims);
%

T=length(Y);
NAR=1;
M=50;
H=12;
%
N=size(Y,2);
results=fvar(Y,NAR);
MPHI=mphi(results,NAR,N);
%matrix of variances y covariances
for i = 1:N
err(:,i) = results(i).resid;
end
Omega = err'*err/rows(err);
%P=chol(Omega); Choleski factorization
P=eye(N);
