how to get square matrix?

hello i have controller design matlab script and i want to adjust a square matrix dimension of 11*11.

*******************

Q=Csc'*Csc;
f=[0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0;0 0 0 0 0];
g=[0 0 0 0 0 0 0 0 0 0;0 0 0 0 0 0 0 0 0 0;0 0 0 0 0 0 0 0 0 0;0 0 0 0 0 0 0 0 0 0;0 0 0 0 0 0 0 0 0 0];
r=[3.9805e-7 0 0 0 0; 0 0 0 0 4.1623e-5;3.9805e-7 0 0 0 0;0 0 0 0 4.1623e-5;0 0 0 0 0];
n=[Q f; g r];

************************

in the above Q is 10*10 matrix

f is 10*5 matrix 

g is 5*10 matrix

r is 5*5 matrix

because of this i am getting 'n=[Q f; g r]' matrix 15*15 dimension

i want 'n' as a square matrix of 11*11 dimension . how should i adjust the above matrix dimensions ?

Which Matrices are you allowed to change?

[Aniket]

f, g, r matrices

Answer 1

[Azzi Abdelmalek]

f=zeros(10,1)
g=zeros(1,6)
r=zeros(1,5)
r(1,1)=3.9805e-7
n=[Q f; g r];
