My generated matrix has a square bracket at every line, why? How to solve this problem? Many thanks! The codes are as follows.

clear all;
syms kz x y
x=0.5;
y=0;
m = 2;
vh = 4;
mu = 11;
delta = 8;
HBAR = 1.05457266e-34;
ME = 9.1093897e-31;
ELEC = 1.60217733e-19;
Kh = 2.106;
vKh = [0,0,0;Kh,0,0;-Kh,0,0;0,Kh,0;0,-Kh,0];
kc = sqrt(2*ME*ELEC/HBAR^2)*1e-10;
ku = kc*sqrt(mu+delta);
kd = kc*sqrt(mu-delta);
a3 = [pi/Kh,pi/Kh,sqrt(2)*pi/Kh];
kuu =@(x,y) [-ku*sin(x)*cos(y), -ku*sin(x)*sin(y), kz];
n=0:m;
for p=1:5;
    for q=1:5;
    tuu(p,q)=(sum((kuu(x,y) + vKh(p,:)).^2)-ku^2)*(p==q)+ kc^2*vh*sum(exp(i*n*sum((vKh(q,:)-vKh(p,:)).*a3)))*(p~=q);
    end
end
tuu

That's just the way non-scalar symbolic matrices are displayed in the Command Window.

The Live Editor displays symbolic matrices differently. Perhaps that will be more to your liking. See this example that creates and manipulates symbolic matrices. The Linear Algebra section of that example in particular creates matrices b and lambda.
