Need help with using stairs function

Hello, Can someone help me using staris function. When I use the following code, it doesn't show any error but there's only empty figure.

A = [0 0 -2;1 0 -5;0 1 -4];
b = [1;0;0];
c = [8 -26 66];
d = [];
ts = 0.1;

%[ad,bd,cd,dd] = discretise(A,b,c,d,ts);
u = 1;
I = eye(3);
G = expm(A*ts); 
H = inv(A)*(G-I)*b;
x{1} = zeros(3);

%figure

for k=1:1:100
   kT{k}=[0;0;0]+k-1;
   x{k+1}=G*x{k}+H;
   y{k}=c*x{k};  
   
end
for i=1:10:100
    hold on
   stairs(kT{i},y{i});
   %stem(kT{i},y{i}); 
end

Try this:

kTm = cell2mat(kT);
ym  = cell2mat(y.').';

figure
stairs(kTm(1,:), ym(1,:).')
grid

The cell arrays appear to have triplicate rows or columns, so convert them to matrices, transpose ‘y’, and choose one row of each to plot.

It works perfectly. Thank you.
