I want to store the results from an iterative video processing, which means I am getting data from every single frame on the video.

I am calculating depth estimation from an stereo video, I am calculating:

Frame
Time (video time)
Target World Coordinates (X, Y, Z), where this is a m x 3 matrix
... Among others ...

All this variables are gonna change at every single instant of time, let's say:

Frame will increase for every iteration, i.e. Frame = Frame + 1;
Time will read the instant of time of the video which belongs to the frame beign process, i.e. 1 seg;
Coordinates, where it will store the world coordinates of the targets, i. e, [2 4 5 ; 1 8 9];

For example:

Frame = 0;                    % Frame reader
Time = 0;                     % Time reader
Coordinates = zeros(m , 3)    % World Coordinates
while hasFrame(Video)
    Frame = Frame + 1;         % Increase the counter for the Frames
    
    % { 
         % This Section contains all the video processing
    % }
    
    Coordinates = [X1 Y1 Z1
                   X2 Y2 Z2
                   X3 Y3 Z3
                     ...
                   Xn Yn Zn]; % This will return the world coordinates of the targets that are in the video, this might change in size of rows...
end

I want to store each of the variables avobe in a single object with the following (or similar) format as a class or something.

Frame(1).Time;         % Whatever time is on the video
Frame(1).Coordinates;  % Results from the processing
Frame(2).Time;         % Whatever time is on the video
Frame(2).Coordinates;  % Results from the processing

Is there a way I can achieve what I want?
