Adding elements into array in for loop

Hello everyone, I have a problem with my project, which is little bit complicated, so that I describe it to you briefly:
I have an array named Shody{99*1} cell. I've used Kalman filter and region validation to find the trajectory.
For example, to be simple, I consider Shody{1} = [9 7], Shody{2} = [6 8; 7 7], Shody{3} = [7 4], Shody{4} = [4 8; 7 9], Shody{5} = [8 3]. After using filtering algorithm I will get the trajectorie = [9 7 7 4 8 3], you can see it is like a chain from Shody{1} to Shody{5} ([9 7] [7 7] [7 4] [4 8] [8 3]). With for loop (i = 1:length(Shody)), I just want to get:
When i = 1 => Trajectory = [9 7];
When i = 2 => Trajectory = [9 7 7];
When i = 3 => Trajectory = [9 7 7 4];
When i = 4 => Trajectory = [9 7 7 4 8];
When i = 5 => Trajectory = [9 7 7 4 8 3] ..... up to 99
But I used Trajectory = cat(1, Shody{1}, k) and got a problem like that:
When i = 1 => Trajectory = [9 7];
When i = 2 => Trajectory = [9 7 7];
When i = 3 => Trajectory = [9 7 4];
When i = 4 => Trajectory = [9 7 8];
Can anyone give me some hints, please!
I will give you my file, so that you could understand what I mentioned. It is little complicated, so I am afraid whether I can make you understand my problem or not.
