how to create square matrix ?

i want to create square matrix but it is with at most 1 rows.

Actually i am using Kalman filter command to create estimator but it is giving me some error..

the command is

QN=eye(10);
L= kalman(syssc,QN,QV)

the error is coming for QW

In the "kalman(SYS,QN,RN,NN,...)" command, QN must be a real square matrix with at most 1 rows.

how should i do this ?

What is syssc? continuous or discrete system? provide more information about your system.

[Aniket]

syssc is continuous system, like this

load sec_sumsin_ABCDmatrix.mat % data As,Bs,Cs,Ds 

syss=ss(As,Bs,Cs,Ds,0.001);

syssc=d2c(syss,'tustin');

[Asc,Bsc,Csc,Dsc]=ssdata(syssc);

eye(1) would be a real square matrix with one row.
